Subject Re: Transaction logs not getting deleted

Are you saying that you are not able index at ll for the past  2 days?.Can
you tell me if leaders for all shards are up.There could be large tlog
files when you set auto commit  to a higher value.Check in the logs if
 tlog is getting replayed.I have used only 4.4 and with it the  tlog replay
 was slow.One thing we did was to shut down  solr instance,remove tlog from
the recovering replica and restart(for huge tlogs).It  did a full copy of
the index  from  the leader.It depends on your index size and I/O on how
fast it would be.I am not sure if there is a better solution to this.

This is a very nice blog that I read...
