# A node can have generic attributes associated with it, which can later be used
# for customized shard allocation filtering, or allocation awareness. An attribute
# is a simple key value pair, similar to node.key: value, here is an example:
# 一个节点可以附带一些普通的属性，这些属性可以在后面的自定义分片分配过滤或者allocation awareness中使用。
# 一个属性就是一个简单的键值对，类似于node.key: value, 这里有一个例子：
#
# node.rack: rack314
# By default, multiple nodes are allowed to start from the same installation location
# to disable it, set the following:
# 默认的，多个节点允许从同一个安装位置启动。若想禁止这个特性，按照下面所示配置：
# node.max_local_storage_nodes: 1

# You can set a number of options (such as shard/replica options, mapping
# or analyzer definitions, translog settings, ...) for indices globally,
# in this file.
# 你可以在这个文件中为所有的索引设置一系列的全局操作(例如 分片/副本 操作，mapping(映射)
# 或者分词器定义，translog配置,...)
#
#
# Note, that it makes more sense to configure index settings specifically for
# a certain index, either when creating it or by using the index templates API.
# 提示，针对一个特定的索引进行配置更合理，不论是在创建索引还是使用索引模板API的时候。

# Set the number of shards (splits) of an index (5 by default):
# 设置一个索引的分片数量(默认为5)
#
# index.number_of_shards: 5
# Set the number of replicas (additional copies) of an index (1 by default):
# 设置一个索引的副本数量(默认为1)
#
# index.number_of_replicas: 1
# Note, that for development on a local machine, with small indices, it usually
# makes sense to "disable" the distributed features:
# 注意，为了使用小的索引在本地机器上开发，禁用分布式特性是合理的做法。
#
#
# index.number_of_shards: 1
# index.number_of_replicas: 0
# These settings directly affect the performance of index and search operations
# in your cluster. Assuming you have enough machines to hold shards and
# replicas, the rule of thumb is:
# 这些设置会直接影响索引和查询操作的在集群中的性能。假如你有足够的机器来放分片和副本，
# 最佳实践是:
#
# 1. Having more *shards* enhances the _indexing_ performance and allows to
# _distribute_ a big index across machines.
# 1. 索引分片分的多一些，可以提高索引的性能，并且把一个大的索引分布到机器中去。
# 2. Having more *replicas* enhances the _search_ performance and improves the
# cluster _availability_.
# 2. 副本分片分的多一些，可以提高搜索的性能，并且提高集群的可用性。
#
# The "number_of_shards" is a one-time setting for an index.
# "number_of_shards"对一个索引来说只能配置一次
#
# The "number_of_replicas" can be increased or decreased anytime,
# by using the Index Update Settings API.
# "number_of_replicas"在任何时候都可以增加或减少，通过Index Update Settings(索引更新配置)API可以做到这一点。
#
#
# ElasticSearch takes care about load balancing, relocating, gathering the
# results from nodes, etc. Experiment with different settings to fine-tune
# your setup.
# ElasticSearch 会维护load balancin(负载均衡),relocating(重定位),合并来自各个节点的结果等等。
# 你可以实验不同的配置来进行优化。
#
# Use the Index Status API (<:9200/A/_status>) to inspect
# the index status.
# 使用Index Status(索引状态)API (<:9200/A/_status>)查看索引状态
