David Smiley commented on SOLR-15585:
-------------------------------------
Are we calling this "data loss" for the duration of time that the TLOGs are
unavailable? This is to be expected, in my mind. I'm hesitant to even call
that "data loss". It's not lost; it's pending the replica returning.
> Graceful shutdown can cause data loss with PULL replicas

> URL: https://issues.apache.org/jira/browse/SOLR-15585
> Project: Solr
> Issue Type: Bug
> Reporter: Ishan Chattopadhyaya
> Priority: Major
>
> When using TLOG (leader)+PULL replicas, a clean shutdown of the node
> containing leaders (for which PULL replicas exist on other nodes) can be
> complete even before PULL replicas get a chance to sync all recently
> committed segments. One solution can be to have a check and enforce a
> replication on the node containing the leaders of such shards before shutting
> down.
