[jira] [Created] (SOLR-11718) Deprecate CDCR Buffer APIs

Amrit Sarkar created SOLR-11718:
-----------------------------------

             Summary: Deprecate CDCR Buffer APIs
                 Key: SOLR-11718
                 URL: https://issues.apache.org/jira/browse/SOLR-11718
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: CDCR
    Affects Versions: 7.1
            Reporter: Amrit Sarkar
             Fix For: 7.2


Kindly see the discussion on SOLR-11652.

Today, if we see the current CDCR documentation page, buffering is "disabled" by default in both source and target. We don't see any purpose served by Cdcr buffering and it is quite an overhead considering it can take a lot heap space (tlogs ptr) and forever retention of tlogs on the disk when enabled. Also today, even if we disable buffer from API on source , considering it was enabled at startup, tlogs are never purged on leader node of shards of source, refer jira: SOLR-11652
