| | | | |
| − | * '''New fast query cache !'''
| + | === Missing regression test suite in pgpool-II 3.3.0.tar.gz (2013/07/31) === |
| − | : On memory query cache is faster because cache storage is on memory. Moreover you don't need to restart pgpool-II when the cache is outdated because the underlying table gets updated.
| |
| − | : On memory cache saves pair of SELECT statements (with its Bind parameters if the SELECT is an extended query). If the same SELECTs comes in, it returns the value from cache. Since no SQL parsing nor access to PostgreSQL are involed, it's extremely fast.
| |
| | | | |
| − | * '''Choosing cache storage'''
| + | New regression test suite was not accidentally included in the pgpool-II 3.3.0.tar.gz tar ball. |
| − | : You can choose a cache storage: shared memory or memcached (you can't use the both).
| + | You can get it from git repository or download from |
| − | : Query cache with shared memory is fast and easy because you don't have to install and config memcached, but restricted the max size of cache by the one of shared memory. Query cache with memcached needs a overhead to access network, but you can set the size as you like. | + | [http://www.pgpool.net/download.php?f=regression-3.3.0.tar.gz here]. |

| | | | |
| − | * '''Life checking of pgpool service'''
| + | You can download them [http://pgpool.net/mediawiki/index.php/Downloads here]. |
| − | : Watchdog monitors responses of pgpool service rather than process. It sends queries to PostgreSQL via pgpool which is being monitored by watchdog and watchdog checks the response. | |
| − | : Also watchdog monitors connections to up stream servers (application servers etc.) from the pgpool.
| |
| − | : The connection between the up stream servers and the pgpool is monitored as service of pgpool.
| |
| | | | |
| − | * '''Mutually monitoring of watchdog processes'''
| + | V3.3's new features are: |
| − | : Watchdog processes exchange information on the monitored servers to keep the information up to date, and to allow watchdog processes to mutually monitor each other. | |
| | | | |
| − | * '''Changing active/standby state in case of certain faults detected''' | + | * Enhancements for watchdog |
| − | : When a fault is detected in the pgpool service, watchdog notifies the other watchdogs of it. Watchdogs decide the new active pgpool if previous active pgpool is broken by voting and change active/standby state.
| + | ** New monitoring method of watchdog lifecheck using heartbeat signal |
| − | | + | ** Interlocking of failover/failback script |
| − | * '''Automatic virtual IP address assigning synchronous to server switching''' | + | ** Secure watchdog communication |
| − | : When a standby pgpool server promotes to active, the new active server brings up virtual IP interface. Meanwhile, the previous active server brings down the virtual IP interface.
| + | ** PCP command for retrieving the watchdog status |
| − | : This enables the active pgpool to work using the same IP address even when servers is switched over.
| + | ** etc. |
| − | | + | * Othres |
| − | * '''Automatic registration of a server as standby in recovery''' | + | ** Import PostgreSQL 9.2 raw parser |
| − | : When broken server recovers or new server is attached, the watchdog process notifies the other watchdog process along with information of the new server, and the watchdog process receives information on the active server and other servers. Then, the attached server is registered as standby.
| + | ** New pgpool_setup tool |

Welcome to Pgpool Wiki!
What is pgpool-II?
pgpool-II is a middleware that works between PostgreSQL servers and a PostgreSQL database client. It is licensed under BSD license. It provides the following features.
- pgpool-II saves connections to the PostgreSQL servers, and reuse them whenever a new connection with the same properties (i.e. username, database, protocol version) comes in. It reduces connection overhead, and improves system's overall throughput.
- pgpool-II can manage multiple PostgreSQL servers. Using the replication function enables creating a realtime backup on 2 or more physical disks, so that the service can continue without stopping servers in case of a disk failure.
- If a database is replicated, executing a SELECT query on any server will return the same result. pgpool-II takes an advantage of the replication feature to reduce the load on each PostgreSQL server by distributing SELECT queries among multiple servers, improving system's overall throughput. At best, performance improves proportionally to the number of PostgreSQL servers. Load balance works best in a situation where there are a lot of users executing many queries at the same time.
- Limiting Exceeding Connections
- There is a limit on the maximum number of concurrent connections with PostgreSQL, and connections are rejected after this many connections. Setting the maximum number of connections, however, increases resource consumption and affect system performance. pgpool-II also has a limit on the maximum number of connections, but extra connections will be queued instead of returning an error immediately.
- Using the parallel query function, data can be divided among the multiple servers, so that a query can be executed on all the servers concurrently to reduce the overall execution time. Parallel query works the best when searching large-scale data.
pgpool-II talks PostgreSQL's backend and frontend protocol, and relays a connection between them. Therefore, a database application (frontend) thinks that pgpool-II is the actual PostgreSQL server, and the server (backend) sees pgpool-II as one of its clients. Because pgpool-II is transparent to both the server and the client, an existing database application can be used with pgpool-II almost without a change to its sources.
