Hi Erick, First of all thanks for your response . I will check the possibility . Let me explain my problem in detail :
1. We have other use cases where we are making use of listener on postCommit to delete/shift/split the shards . So we have capability to delete the shards . 2. The current use case is , where we have to delete the documents from the shard , and during deletion process(it will be scheduled process, may be hourly or daily, which will delete the documents) , if shards gets empty (or may be lets say nominal documents are left ) , then delete the shard. And I am exploring to do this using configuration . Regards Pushkar On Mon, Nov 30, 2020, 8:48 PM Erick Erickson <erickerick...@gmail.com> wrote: > Are you using the implicit router?
