Does elasticsearch can handle concurrency search/aggregation well? (For example, 1000 people issue the same/different query at the same time)
Please note that I am not talking about concurrency update, only search/agg.
Databases like oracle/mysql all talking about concurrency in there docs. Did not find elasticsearch talking about this. Does that mean concurrency is not a problem to the data structure and architecture of elasticsearch?
I know cache of filter is one good thing to make concurrency query easier. Anything else?
