The minimum number of connections the pool will hold. The maximum number of connections limits the number of concurrent requests that can be made against the database. When the maximum number of connections is exceeded, additional requests that require a database connection will be halted until a connection from the pool becomes available and eventually times out if that’s not possible within the time specified in the connection time-out. The maximum number of connections the pool can hold. Baseline is, one way or the other you’ll always end-up using a connection pool in GeoServer. In most GeoServer DataStores you have the possibility to use the JNDI or the standard store which basically means you can have GeoServer manage the connection pool for you or you can configure it externally (from within the Application Server of choice) and then have GeoServer lean onto it to get connections. Ok, now let’s go into GeoServer specifics. The benefit is that connection set-up only need to occur once on the first request while subsequent requests use existing connections and achieve a performance benefit as a result. The purpose served by a connection pool is to maintain connections to an underlying database between requests. limit the lifetime of connections created in order to discourage clients from retaining connections for a really long time.PostgreSQL by default has a limit set to 100) limit the number of connections globally available (e.g. ![]() ![]() as a consequence of the fact that a connection require non negligible resources on the server DBMS DBAs tend to.being processes that means that creating a connection is not a zero-cost process therefore we should avoid creating connections as we need to connect to a DB but we should tend to create them in advance in order to minimize the impact of the time needed to create them on the time needed to serve a request.they are heavy to create and maintain for the database server itself since they are usually child processes of the DBMS server process.Advanced Database Connection Pooling Configuration ¶ Database connections are valuable resources and as such shall be managed with care:
