Description:
pgpool-II is a inherited project of pgpool (to classify from pgpool-II, it is sometimes called as pgpool-I). For those of you not familiar with pgpool-I, it is a multi-functional middle ware for PostgreSQL that features connection pooling, replication and load balancing functions. pgpool-I allows a user to connect at most two PostgreSQL servers for higher availability or for higher search performance compared to a single PostgreSQL server. pgpool-II, on the other hand, allows multiple PostgreSQL servers (DB nodes) to be connected, which enables queries to be executed simultaneously on all servers. In other words, it enables "parallel query" processing. Also, pgpool-II can be started as pgpool-I by changing configuration parameters. pgpool-II that is executed in pgpool-I mode enables multiple DB nodes to be connected, which was not possible in pgpool-I.
