initializationFailTimeout property in HikariCP

Question

From Github:

Any positive number is taken to be the number of milliseconds to attempt to acquire an initial connection; the application thread will be blocked during this period. Default: 1

I understand when using default value if connection is not obtained within 1 sec then error will be thrown .I am planning to set the value as 1000 ms as sometimes I am getting the error as

"hikaripool$poolinitializationexception"

when starting the spring boot Java 8 app. Is this the correct approach?

Answer 1

Not exactly it wait for connection connectTimeout + initializationFailTimeout , from github:

This timeout is applied after the connectionTimeout period

Which is by default half a minute

Default: 30000 (30 seconds)

You can enter -1 value to allow pool to start without failing

A value less than zero will bypass any initial connection attempt, and the pool will start immediately while trying to obtain connections in the background
