What is the ideal bulk size formula in ElasticSearch? -

-

i believe there should formula calculate bulk indexing size in elasticsearch. followings variables of such formula.

  • number of nodes
  • number of shards/index
  • document size
  • ram
  • disk write speed
  • lan speed

i wonder if know or use mathematical formula. if not, how people decide bulk size? trial , error?

there no golden rule this. extracted doc:

there no “correct” number of actions perform in single bulk call. should experiment different settings find optimum size particular workload.
