Steph van Schalkwyk commented on CONNECTORS-1546:
-
Hans is correct. I would remove it. It can mess up merging later if not used
correctly. It may also take a long time to complete.
I'm going to upload a patch or two soon and will remove it if you concur.
BTW, from the ES 6.4 doc:
"Force merge should only be called against *read-only indices*. Running force
merge against a read-write index can cause very large segments to be produced
(>5Gb per segment), and the merge policy +*will never consider it for merging
again until it mostly consists of deleted docs*+. This can cause very large
segments to remain in the shards."
But I agree. It isn't up to MCF to decide what to do as it does impact
ingesting.
Hans may want to try this before ingesting:
PUT /_cluster/settings{"transient" : {"indices.store.throttle.type" : "none"
}}
and after ingesting:
PUT /_cluster/settings{"transient" : {"indices.store.throttle.type" : "merge"
}}
