Force Merge Action
Content
The force merge action forces the reduction of segments for each shard. This potentially frees up space by removing deleted documents.
The segments parameter specifies the number of segments each shard should be merged to.
Since force merges can be costly, this action is implemented asynchronously, meaning a separate internal step is automatically added to the policy to check if the force merge has finished.
Until the force merge is finished successfully, the index remains in the internal awaiting_force_merge step.
No other steps, actions or conditions are run during this phase.
Asynchronous actions are always required to be the last action in a step.
