START_MEREQ Handling .483 6.6 NDB Internals Glossary 483 Index 485 vii Chapter Overview and Concepts This chapter provides a general overview of essential MySQL Cluster, NDB API, and MGM API concepts, terminology, and programming constructs For an overview of Java APIs that can be used with MySQL Cluster, see Section 4.1, “MySQL Cluster Connector for Java: Overview” 1.1 Introduction This section introduces the NDB Transaction and Scanning APIs as well as the NDB Management (MGM) API for use in building applications to run on MySQL Cluster It also discusses the general theory and principles involved in developing such applications 1.1.1 The NDB API The NDB API is an object-oriented application programming interface for MySQL Cluster that implements indexes, scans, transactions, and event handling NDB transactions are ACID-compliant in that they provide a means to group operations in such a way that they succeed (commit) or fail as a unit (rollback) It is also possible to perform operations in a "no-commit" or deferred mode, to be committed at a later time NDB scans are conceptually rather similar to the SQL cursors implemented in MySQL 5.0 and other common enterprise-level database management systems These provide high-speed row processing for record retrieval purposes (MySQL Cluster naturally supports set processing just as does MySQL in its non-Cluster distributions This can be accomplished through the usual MySQL APIs discussed in the MySQL Manual and elsewhere.) The NDB API supports both table scans and row scans; the latter can be performed using either unique or ordered indexes Event detection and handling is discussed in Section 2.3.11, “The NdbEventOperation Class”, as well as Section 2.4.8, “NDB API Event Handling Example” In addition, the NDB API provides object-oriented error-handling facilities in order to provide a means of recovering gracefully from failed operations and other problems See Section 2.4.3, “Handling Errors and Retrying Transactions”, for a detailed example The NDB API provides a number of classes implementing the functionality described above The most important of these include the Ndb, Ndb_cluster_connection, NdbTransaction, and NdbOperation classes These model (respectively) database connections, cluster connections, transactions, and operations These classes and their subclasses are listed in Section 2.3, “NDB API Classes, Interfaces, and Structures” Error conditions in the NDB API are handled using NdbError, a structure which is described in Section 2.3.31, “The NdbError Structure” 1.1.2 The MGM API The MySQL Cluster Management API, also known as the MGM API, is a C-language programming interface intended to provide administrative services for the cluster These include starting and stopping Cluster nodes, handling Cluster logging, backups, and restoration from backups, as well as various other management tasks A conceptual overview of MGM and its uses can be found in Chapter 3, The MGM API The MGM API's principal structures model the states of individual modes (ndb_mgm_node_state), the state of the Cluster as a whole (ndb_mgm_cluster_state), and management server response messages (ndb_mgm_reply) See Section 3.4, “MGM Structures”, for detailed descriptions of these 1.2 Terminology Provides a glossary of terms which are unique to the NDB and MGM APIs, or have a specialized meaning when applied therein The terms in the following list are useful to an understanding of MySQL Cluster, the NDB API, or have a specialized meaning when used in one of these contexts See also MySQL Cluster Overview, in the MySQL Manual • Backup: A complete copy of all cluster data, transactions and logs, saved to disk • Restore: Returning the cluster to a previous state as stored in a backup • Checkpoint: Generally speaking, when data is saved to disk, it is said that a checkpoint has been reached When working with the NDB storage engine, there are two sorts of checkpoints which work together in order to ensure that a consistent view of the cluster's data is maintained: • Local Checkpoint (LCP): This is a checkpoint that is specific to a single node; however, LCPs take place for all nodes in the cluster more or less concurrently An LCP involves saving all of a node's data to disk, and so usually occurs every few minutes, depending upon the amount of data stored by the node Overview and Concepts More detailed information about LCPs and their behavior can be found in the MySQL Manual, in the sections Defining MySQL Cluster Data Nodes, and Configuring MySQL Cluster Parameters for Local Checkpoints • Global Checkpoint (GCP): A GCP occurs every few seconds, when transactions for all nodes are synchronized and the REDO log is flushed to disk A related term is GCI, which stands for “Global Checkpoint ID” This marks the point in the REDO log where a GCP took place • Node: A component of MySQL Cluster node types are supported: • Management (MGM) node: This is an instance of ndb_mgmd, the cluster management server daemon • Data node (sometimes also referred to as a “storage nodes”, although this usage is now discouraged): This is an instance of ndbd, and stores cluster data • API node: This is an application that accesses cluster data SQL node refers to a mysqld process that is connected to the cluster as an API node For more information about these node types, please refer to Section 1.3.3, “Review of MySQL Cluster Concepts”, or to MySQL Cluster Programs, in the MySQL Manual • Node Failure: MySQL Cluster is not solely dependent upon the functioning of any single node making up the cluster, which can continue to run even when one node fails • Node Restart: The process of restarting a cluster node which has stopped on its own or been stopped deliberately This can be done for several different reasons, including the following: • Restarting a node which has shut down on its own (when this has occurred, it is known as forced shutdown or node failure; the other cases dicussed here involve manually shutting down the node and restarting it) • To update the node's configuration • As part of a software or hardware upgrade • In order to defragment the node's DataMemory • Initial Node Restart: The process of starting a cluster node with its file system removed This is sometimes used in the course of software upgrades and in other special circumstances • System Crash (or System Failure): This can occur when so many cluster nodes have failed that the cluster's state can no longer be guaranteed • System Restart: The process of restarting the cluster and reinitialising its state from disk logs and checkpoints This is required after either a planned or an unplanned shutdown of the cluster • Fragment: Contains a portion of a database table; in other words, in the NDB storage engine, a table is broken up into and stored as a number of subsets, usually referred to as fragments A fragment is sometimes also called a partition • Replica: Under the NDB storage engine, each table fragment has number of replicas in order to provide redundancy • Transporter: A protocol providing data transfer across a network The NDB API supports different types of transporter connections: TCP/IP (local), TCP/IP (remote), SCI, and SHM TCP/IP is, of course, the familiar network protocol that underlies HTTP, FTP, and so forth, on the Internet SCI (Scalable Coherent Interface) is a high-speed protocol used in building multiprocessor systems and parallel-processing applications SHM stands for Unix-style shared memory segments For an informal introduction to SCI, see this essay at dolphinics.com • NDB: This originally stood for “Network Database” It now refers to the storage engine used by MySQL AB to enable its MySQL Cluster distributed database • ACC: Access Manager Handles hash indexes of primary keys providing speedy access to the records • TUP: Tuple Manager This handles storage of tuples (records) and contains the filtering engine used to filter out records and attributes when performing reads or updates • TC: Transaction Coordinator Handles co-ordination of transactions and timeouts; serves as the interface to the NDB API for indexes and scan operations 1.3 The NDBCLUSTER Transaction and Scanning API Overview and Concepts This section defines and discusses the high-level architecture of the NDB API, and introduces the NDB classes which are of greatest use and interest to the developer It also covers most important NDB API concepts, including a review of MySQL Cluster Concepts 1.3.1 Core NDB API Classes The NDB API is a MySQL Cluster application interface that implements transactions It consists of the following fundamental classes: • Ndb_cluster_connection represents a connection to a cluster See Section 2.3.24, “The Ndb_cluster_connection Class” • Ndb is the main class, and represents a connection to a database See Section 2.3.8, “The Ndb Class” • NdbDictionary provides meta-information about tables and attributes See Section 2.3.10, “The NdbDictionary Class” • NdbTransaction represents a transaction See Section 2.3.19, “The NdbTransaction Class” • NdbOperation represents an operation using a primary key See Section 2.3.15, “The NdbOperation Class” • NdbScanOperation represents an operation performing a full table scan See Section 2.3.18, “The NdbScanOperation Class” • NdbIndexOperation represents an operation using a unique hash index See Section 2.3.12, “The NdbIndexOperation Class” • NdbIndexScanOperation represents an operation performing a scan using an ordered index See Section 2.3.13, “The NdbIndexScanOperation Class” • NdbRecAttr represents an attribute value See Section 2.3.16, “The NdbRecAttr Class” In addition, the NDB API defines an NdbError structure, which contains the specification for an error It is also possible to receive events triggered when data in the database is changed This is accomplished through the NdbEventOperation class Important The NDB event notification API is not supported prior to MySQL 5.1 (Bug#19719) For more information about these classes as well as some additional auxiliary classes not listed here, see Section 2.3, “NDB API Classes, Interfaces, and Structures” 1.3.2 Application Program Basics The main structure of an application program is as follows: Connect to a cluster using the Ndb_cluster_connection object Initiate a database connection by constructing and initialising one or more Ndb objects Identify the tables, columns, and indexes on which you wish to operate, using NdbDictionary and one or more of its subclasses MySQL Cluster Internals Part of this protocol consists of Steps - during the system restart phase as described below This means that restoration of all the fragments, preparation for execution of the redo log, execution of the redo log, and finally reporting back to DBDIH when the execution of the redo log is completed, are all part of this process After preparations are complete, copy phase for each fragment in the node must be performed The process of copying a fragment involves the following steps: The DBLQH kernel block in the starting node is informed that the copy process is about to begin by sending it a PREPARE_COPY_FRAGREQ signal When DBLQH acknowledges this request a CREATE_FRAGREQ signal is sent to all nodes notify them of the preparation being made to copy data to this replica for this table fragment After all nodes have acknowledged this, a COPY_FRAGREQ signal is sent to the node from which the data is to be copied to the new node This is always the primary replica of the fragment The node indicated copies all the data over to the starting node in response to this message After copying has been completed, and a COPY_FRAGCONF message is sent, all nodes are notified of the completion through an UPDATE_TOREQ signal After all nodes have updated to reflect the new state of the fragment, the DBLQH kernel block of the starting node is informed of the fact that the copy has been completed, and that the replica is now up-to-date and any failures should now be treated as real failures The new replica is transformed into a primary replica if this is the role it had when the table was created After completing this change another round of CREATE_FRAGREQ messages is sent to all nodes informing them that the takeover of the fragment is now committed After this, process is repeated with the next fragment if another one exists When there are no more fragments for takeover by the node, all nodes are informed of this by sending an UPDATE_TOREQ signal sent to all of them 10 Wait for the next complete local checkpoint to occur, running from start to finish 11 The node states are updated, using a complete global checkpoint As with the local checkpoint in the previous step, the global checkpoint must be permitted to start and then to finish 12 When the global checkpoint has completed, it will communicate the successful local checkpoint of this node restart by sending an END_TOREQ signal to all nodes 13 A START_COPYCONF is sent back to the starting node informing it that the node restart has been completed 14 Receiving the START_COPYCONF signal ends NDB_STTOR phase This provides another synchronization point for system restarts, designated as WAITPOINT_5_2 Note The copy process in this phase can in theory be performed in parallel by several nodes However, all messages from the master to all nodes are currently sent to single node at a time, but can be made completely parallel This is likely to be done in the not too distant future In an initial and an initial node restart, the SUMA block requests the subscriptions from the SUMA master node NDBCNTR executes NDB_STTOR phase No other NDBCNTR activity takes place 6.5.14 NDB_STTOR Phase In this NDB_STTOR phase, both DBLQH and DBDICT clear their internal representing the current restart type The DBACC block resets the system restart flag; DBACC and DBTUP start a periodic signal for checking memory usage once per second DBTC sets an internal variable indicating that the system restart has been completed 6.5.15 STTOR Phase The NDBCNTR block defines the cluster's node groups, and the DBUTIL block initializes a number of data structures to facilitate the sending keyed operations can be to the system tables DBUTIL also sets up a single connection to the DBTC kernel block 481 MySQL Cluster Internals 6.5.16 STTOR Phase In QMGR the president starts an arbitrator (unless this feature has been disabled by setting the value of the ArbitrationRank configuration parameter to for all nodes—see Defining a MySQL Cluster Management Server, and Defining SQL and Other API Nodes in a MySQL Cluster, for more information; note that this currently can be done only when using MySQL Cluster Carrier Grade Edition) In addition, checking of API nodes through heartbeats is activated Also during this phase, the BACKUP block sets the disk write speed to the value used following the completion of the restart The master node during initial start also inserts the record keeping track of which backup ID is to be used next The SUMA and DBTUX blocks set variables indicating start phase has been completed, and that requests to DBTUX that occurs when running the redo log should no longer be ignored 6.5.17 STTOR Phase NDB_STTOR executes NDB_STTOR phase 7; no other NDBCNTR activity takes place 6.5.18 NDB_STTOR Phase If this is a system restart, the master node initiates a rebuild of all indexes from DBDICT during this phase The CMVMI kernel block opens communication channels to the API nodes (including MySQL servers acting as SQL nodes) Indicate in globalData that the node is started 6.5.19 STTOR Phase NDBCNTR resets some start variables 6.5.20 STTOR Phase 101 This is the SUMA handover phase, during which a GCP is negotiated and used as a point of reference for changing the source of event and replication subscriptions from existing nodes only to include a newly started node 6.5.21 System Restart Handling in Phase This consists of the following steps: The master sets the latest GCI as the restart GCI, and then synchronizes its system file to all other nodes involved in the system restart The next step is to synchronize the schema of all the nodes in the system restart This is performed in 15 passes The problem we are trying to solve here occurs when a schema object has been created while the node was up but was dropped while the node was down, and possibly a new object was even created with the same schema ID while that node was unavailable In order to handle this situation, it is necessary first to re-create all objects that are supposed to exist from the viewpoint of the starting node After this, any objects that were dropped by other nodes in the cluster while this node was “dead” are dropped; this also applies to any tables that were dropped during the outage Finally, any tables that have been created by other nodes while the starting node was unavailable are re-created on the starting node All these operations are local to the starting node As part of this process, is it also necessary to ensure that all tables that need to be re-created have been created locally and that the proper data structures have been set up for them in all kernel blocks After performing the procedure described previously for the master node the new schema file is sent to all other participants in the system restart, and they perform the same synchronization All fragments involved in the restart must have proper parameters as derived from DBDIH This causes a number of START_FRAGREQ signals to be sent from DBDIH to DBLQH This also starts the restoration of the fragments, which are restored one by one and one record at a time in the course of reading the restore data from disk and applying in parallel the restore data read from disk into main memory This restores only the main memory parts of the tables Once all fragments have been restored, a START_RECREQ message is sent to all nodes in the starting cluster, and then all undo logs for any Disk Data parts of the tables are applied After applying the undo logs in LGMAN, it is necessary to perform some restore work in TSMAN that requires scanning the extent headers of the tablespaces Next, it is necessary to prepare for execution of the redo log, which log can be performed in up to four phases For each fragment, execution of redo logs from several different nodes may be required This is handled by executing the redo logs in different phases for a specific fragment, as decided in DBDIH when sending the START_FRAGREQ signal An EXEC_FRAGREQ signal is sent for each phase and fragment that requires execution in this phase After these signals are sent, an EXEC_SRREQ 482 MySQL Cluster Internals signal is sent to all nodes to tell them that they can start executing the redo log Note Before starting execution of the first redo log, it is necessary to make sure that the setup which was started earlier (in Phase 4) by DBLQH has finished, or to wait until it does before continuing Prior to executing the redo log, it is necessary to calculate where to start reading and where the end of the REDO log should have been reached The end of the REDO log should be found when the last GCI to restore has been reached After completing the execution of the redo logs, all redo log pages that have been written beyond the last GCI to be restore are invalidated Given the cyclic nature of the redo logs, this could carry the invalidation into new redo log files past the last one executed After the completion of the previous step, DBLQH report this back to DBDIH using a START_RECCONF message 10 When the master has received this message back from all starting nodes, it sends a NDB_STARTCONF signal back to NDBCNTR 11 The NDB_STARTCONF message signals the end of STTOR phase to NDBCNTR, which is the only block involved to any significant degree in this phase 6.5.22 START_MEREQ Handling The first step in handling START_MEREQ is to ensure that no local checkpoint is currently taking place; otherwise, it is necessary to wait until it is completed The next step is to copy all distribution information from the master DBDIH to the starting DBDIH After this, all metadata is synchronized in DBDICT (see Section 6.5.21, “System Restart Handling in Phase 4”) After blocking local checkpoints, and then synchronizing distribution information and metadata information, global checkpoints are blocked The next step is to integrate the starting node in the global checkpoint protocol, local checkpoint protocol, and all other distributed protocols As part of this the node status is also updated After completing this step the global checkpoint protocol is permitted to start again, the START_MECONF signal is sent to indicate to the starting node that the next phase may proceed 6.6 NDB Internals Glossary This section contains terms and abbreviations that are found in or useful to understanding the NDB source code • ACC ACCelerator or ACCess manager Handles hash indexes of primary keys, providing fast access to records See Section 6.4.3, “The DBACC Block” • API node In NDB
