Overview

When the space uses RDBMS for persistency, it creates a connection pool to avoid a new connection creation with every access to the database. The space schema file stores the pool minimum and maximum size:

<space-config>
	<init_sa_connections>10</init_sa_connections>
	<max_sa_connections>100</max_sa_connections>
</space-config>
Tag Description Default Value
<init_sa_connections> Connection pool minimum size 10
<max_sa_connections> Connection pool maximum size 100
When the engine requests a connection from the pool and there is none available (maximum number of connections have been allocated), the engine waits for a context to become available. This is transparent to the application.
