Segments are, periodically, merged into larger segments to keep the
index size at bay and expunge deletes.
The more segments one has in the Lucene index means slower searches and
more memory used. Segment merging is used to reduce the number of segments,
however merges can be expensive to perform, especially on low IO environments.
Merges can be throttled using <<store-throttling,store level throttling>>.

[[store-throttling]]
=== Store Level Throttling
The way Lucene, the IR library elasticsearch uses under the covers,
works is by creating immutable segments (up to deletes) and constantly
merging them (the merge policy settings allow to control how those
merges happen). The merge process happens in an asynchronous manner
without affecting the indexing / search speed. The problem though,
especially on systems with low IO, is that the merge process can be
expensive and affect search / index operation simply by the fact that
the box is now taxed with more IO happening.
The store module allows to have throttling configured for merges (or
all) either on the node level, or on the index level. The node level
throttling will make sure that out of all the shards allocated on that
node, the merge process won't pass the specific setting bytes per
second. It can be set by setting `indices.store.throttle.type` to
`merge`, and setting `indices.store.throttle.max_bytes_per_sec` to
something like `5mb`. The node level settings can be changed dynamically
using the cluster update settings API. The default is disabled (set to `none`),
in favor of <merge,auto throttle in the merge scheduler>.
If specific index level configuration is needed, regardless of the node
level settings, it can be set as well using the
`index.store.throttle.type`, and
`index.store.throttle.max_bytes_per_sec`. The default value for the type
is `node`, meaning it will throttle based on the node level settings and
participate in the global throttling happening. Both settings can be set
using the index update settings API dynamically.
