editbloom
editBeginning with version 1.4, Elasticsearch no longer enables bloom filters for search. This command is unnecessary if your Elasticsearch version is 1.4 or higher.
Summary
editFrom the Elasticsearch Bloom Filter Posting Format documentation
It can sometime make sense to disable bloom filters. For instance, if you are logging into an index per day, and you have thousands of indices, the bloom filters can take up a sizable amount of memory. For most queries you are only interested in recent indices, so you don’t mind CRUD operations on older indices taking slightly longer.
In these cases you can disable loading of the bloom filter on a per-index basis by updating the index settings
This setting is especially relevant to Logstash and Marvel use-cases. The
bloom
command allows you to disable the bloom filter cache for indices.
Flags
edit$ curator bloom --help Usage: curator bloom [OPTIONS] COMMAND [ARGS]... Disable bloom filter cache Options: --delay INTEGER Pause *n* seconds after disabling bloom filter cache of an index [default: 0] --help Show this message and exit. Commands: indices Index selection.
This command requires the indices subcommand for index selection.
