=== Indexing Buffer
=== 索引缓冲区

索引缓冲区用来存储新索引的文档。当它填满后，缓冲区中的文档被写入磁盘上的一个段。它（缓冲区）分散在节点上的所有分片之间。

以下设置是 _静态_ 的，必须在群集中的每个数据节点上配置：
The 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.

`indices.memory.index_buffer_size`::

Accepts either a percentage or a byte size value. It defaults to `10%`,
meaning that `10%` of the total heap allocated to a node will be used as the
indexing buffer size shared across all shards.
接受百分比或字节大小值。默认为 `10%`，意味着分配给节点的总堆内存的 `10%` 将用作索引缓冲区大小，并在所有分片中共享。

`indices.memory.min_index_buffer_size`::

If the `index_buffer_size` is specified as a percentage, then this
setting can be used to specify an absolute minimum. Defaults to `48mb`.
如果将 `index_buffer_size` 指定为百分比，则设置可用于指定绝对最小值。默认为 `48MB`。

`indices.memory.max_index_buffer_size`::

If the `index_buffer_size` is specified as a percentage, then this
setting can be used to specify an absolute maximum. Defaults to unbounded.
如果将 `index_buffer_size` 指定为百分比，则设置可用于指定绝对最大值。默认为无边界。
