WARNING: Version 1.3 of Elasticsearch has passed its EOL date.
This documentation is no longer being maintained and may be removed. If you are running this version, we strongly advise you to upgrade. For the latest information, see the current release documentation.
Indices
editIndices
editThe indices module allow to control settings that are globally managed for all indices.
Indexing Buffer
editThe indexing buffer setting allows to control how much memory will be allocated for the indexing process. It is a global setting that bubbles down to all the different shards allocated on a specific node.
The indices.memory.index_buffer_size
accepts either a percentage or a
byte size value. It defaults to 10%
, meaning that 10%
of the total
memory allocated to a node will be used as the indexing buffer size.
This amount is then divided between all the different shards. Also, if
percentage is used, it is possible to set min_index_buffer_size
(defaults to
48mb
) and max_index_buffer_size
(defaults to unbounded).
The indices.memory.min_shard_index_buffer_size
allows to set a hard
lower limit for the memory allocated per shard for its own indexing
buffer. It defaults to 4mb
.
TTL interval
editYou can dynamically set the indices.ttl.interval
, which allows to set how
often expired documents will be automatically deleted. The default value
is 60s.
The deletion orders are processed by bulk. You can set
indices.ttl.bulk_size
to fit your needs. The default value is 10000.
