Large garbage collection


I am running constant indexing of ~500/s and ~3000/s reads on my cluster, and during that I see big drops in heap usage on the data nodes:

5 master nodes
7 data nodes
2 coordinator nodes

Is that an expected behavior or are there any changes that need to be done in regard of the garbage collection?


That's expected yes.

Please read those 4 documents:

Tons of reading material but after the above I would guess you'd be at least in the 90th percentile in regards to "heap on ES". Complement as you go along or on an as needed basis.
