Re: Timeouts in Postgresql JDBC Driver

Hi Debraj,

See which of these option works best for you

Client side Timeouts ... socketTimeout, loginTimeout, connectTimeout
Server side Timeouts ... statement_timeout
If you are using connection pooling e.g. HikariCP then you may set
setConnectionTimeout, setIdleTimeout, setMaxLifetime

Regards,
