I am struggling a bit to understand which ES operations use up which part
- From reading the documentation I know that faceting and sorting take up
heap memory and also that some filters are cached in JVM heap. However,
what other operations take up JVM heap memory?
- When faceting on a particular field are all of the values of that field
loaded into JVM heap or only the distinct values of the field. I would
believe it is the latter as fields of high cardinality require more JVM
- What operations use OS memory. I believe documents retrieved and ES index
are kept in OS memory. Can anyone confirm this? What other operations go to
Finally, I would also be interested if there are any posts or tutorials
that desribce the complete lifecycle of a query from submission of query to
return of resultset.
