Pools

A pool is an object that holds a set of client connections. It is subsequently used by the proxy object to manage client and server connections.

The size of the pool defines the maximum capacity of the pool. Upon start, GatewayD creates as many client connections to the database server, e.g. PostgreSQL, as the capacity allows. If GatewayD fails to connect on each connection, it will shut down gracefully and will send an error log to the selected log outputs with the cause.

size	number	10	Positive integers	Since this creates many parallel connections to the database, setting it to a very high value will degrade performance of the database.
