Enum Constant Detail

NEW

public static final QueryStatus.Status NEW

The new.

QUEUED

RUNNING

public static final QueryStatus.Status RUNNING

The running. At this point the query starts running on chosen driver

EXECUTED

The executed. At this point execution is finished by driver, but server may still have some more operations pending like result persistence, if enabled.

FAILING

public static final QueryStatus.Status FAILING

This state is when depending on retry policy, either the query moves to QUEUED (in case retries are to be done), or to FAILED.
