JDBC Driver for Apache Impala

Build 22.0.8462

ConnectOnOpen

This property specifies whether to connect to the Apache Impala when the connection is opened.

Data Type

bool

Default Value

false

Remarks

When set to true, a connection will be made to Apache Impala when the connection is opened. This property enables the Test Connection feature available in various database tools.

This feature acts as a NOOP command as it is used to verify a connection can be made to Apache Impala and nothing from this initial connection is maintained.

Setting this property to false may provide performance improvements (depending upon the number of times a connection is opened).
