Subject If the leader dies, will the data be lost?
Date Mon, 06 Apr 2020 05:53:53 GMT
Hi,
Using solr 7.5.0 on solr cloud, and replica type is tlog.

If a leader dies, how is the re-election of the leader and the
synchronization of the replicas done?

In my opinion.
Leader dies→ New tlog replica tries to become Leader→ Replays tlogs not
reflected in the index→ Becomes Leader
Is this the right fit first?

Also, when another leader is elected, does it create a tlog that is only
available to the old leader? (I'm worried about data being lost if the
tlogs aren't synchronized.)
