Description-en: connection pool server and replication proxy for PostgreSQL
pgpool-II is a middleware that works between PostgreSQL servers and a
PostgreSQL database client. It provides the following features:
.
* Connection Pooling
* Replication
* Load Balance
* Limiting Exceeding Connections
* Parallel Query
.
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.
.
This is version 3 of pgpool-II, the second generation of pgpool.
