Hello, everyone!
I'm tuning ES 6.8 for indexing performance and noticed one interesting thing. There is a significant difference in the default value of the q size in versions 6.8 and 7.x. The documentation states:
ES 6.8
write
For single-document index/delete/update and bulk requests. Thread pool type is fixed
with a size of # of available processors
, queue_size of 200
. The maximum size for this pool is 1 + # of available processors
.
ES 7.x
write
For single-document index/delete/update and bulk requests. Thread pool type is fixed
with a size of # of allocated processors
, queue_size of 10000
. The maximum size for this pool is 1 +
# of allocated processors
.
So, that's 10,000 vs 200.
I'm wondering , would it be recommended to change this value to 10,000 in my version 6.8 cluster and would it improve the situation with 429 errors, keeping in mind that I use separate coordinator nodes and the cluster size is really huge (100+ nodes)
