elasticsearch - what does index.store.fs do -


i under impression use mmapfs store, needed set index.store.type mmapfs, reading article , saw author did this

index:     store:       type: mmapfs       fs:         mmapfs:           enabled: true

so did did set index.store.fs.mmapfs.enabled true

my question whole index.store.fs section , can find documentation on it?

the config need is:

index.store.type: mmapfs

i don't know rest of config taken - maybe older version.

the best place see config settings sure of supported in code itself: https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/index/store/indexstoremodule.java#l57

while on subject of mmapfs, worth reading blog entry: http://blog.thetaphi.de/2012/07/use-lucenes-mmapdirectory-on-64bit.html
