Indexing buffer settings
editIndexing buffer settings
editThe indexing buffer is used to store newly indexed documents. When it fills up, the documents in the buffer are written to a segment on disk. It is divided between all shards on the node.
The following settings are static and must be configured on every data node in the cluster:
-
indices.memory.index_buffer_size -
(Static)
Accepts either a percentage or a byte size value. It defaults to
10%, meaning that10%of the total heap allocated to a node will be used as the indexing buffer size shared across all shards. -
indices.memory.min_index_buffer_size -
(Static)
If the
index_buffer_sizeis specified as a percentage, then this setting can be used to specify an absolute minimum. Defaults to48mb. -
indices.memory.max_index_buffer_size -
(Static)
If the
index_buffer_sizeis specified as a percentage, then this setting can be used to specify an absolute maximum. Defaults to unbounded.
