== Flush
|
||
|
|
|
||
|
|
The flush API allows to flush one or more indices through an API. The
|
||
|
|
flush process of an index basically frees memory from the index by
|
||
|
|
flushing data to the index storage and clearing the internal
|
||
|
|
<<index-modules-translog,transaction log>>. By
|
||
|
|
default, ElasticSearch uses memory heuristics in order to automatically
|
||
|
|
trigger flush operations as required in order to clear memory.

=== Multi Index
|
||
|
|
|
||
|
|
The flush API can be applied to more than one index with a single call,
|
||
|
|
or even on `_all` the indices.
