[jira] [Created] (SOLR-12012) Replicas should skip doing recovery
on startup
Cao Manh Dat created SOLR-12012:
-----------------------------------
Summary: Replicas should skip doing recovery on startup
Key: SOLR-12012
URL: https://issues.apache.org/jira/browse/SOLR-12012
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Cao Manh Dat
Assignee: Cao Manh Dat
Right now a replica when first loaded always does recovery (except the replica is the leader). This will lead to several problems, for example:
- leaderless if at the same time the replica is doing recovery, the current leader goes down.
- the recovery process is not necessary if the replica is already in-sync with the leader
By using term value introduced in SOLR-11702 we can skip the recovery process if replica's term equals to leader's term.
