进阶操作
1.开启、关闭索引通配符删除
false表示可以通配符删除
true表示不可以通配符删除
[PUT] _cluster/settings
{"transient": {"action.destructive_requires_name": false}
}
2.调整集群最大分片数
用于配置生命周期后，自动分裂分片使用
[PUT] _cluster/settings
{"transient": {"cluster.max_shards_per_node": 100000}
}
3.设置Search返回结果最大条数（默认10000）
所有索引生效
[PUT] _all/_settings
{ "index.max_result_window": 50000
}
单个索引生效
[PUT] {index}/_settings
{ "index.max_result_window": 50000
}
4.批量设置索引别名、设置为写索引
同时设置多个在数组里增加即可
“is_write_index”: true表示当多个索引共用同一个别名时，设置当前索引为写索引，读的话走别名，可以将所有索引数据都查到
[POST] _aliases
{"actions": [{"add": {"index": "m12_insertzone-000001","alias": "m12_insertzone","is_write_index": true}}]
}
5.设置索引生命周期模板名称及滚动更新索引别名
[POST] {index}/_settings
{"index.lifecycle.name": "iscas","index.lifecycle.rollover_alias": "m12_insertzone"
}
6.创建索引含配置
[PUT] {index}
{"aliases": {"m12_insertzone": {"is_write_index": true}},"settings": {"index.number_of_shards": "6","index.number_of_replicas": "1","index.lifecycle.name": "iscas-ilm-policy","index.lifecycle.rollover_alias": "m12_insertzone","index": {"routing": {"allocation": {"require": {"hotwarm_type": "hot"}}},"translog": {"durability": "async","sync_interval": "30s","flush_threshold_size": "1024mb"}}},"mappings": {}
}
7. 创建模板含配置
[PUT] _template/{name}
{"index_patterns": ["m22_sample_30-*"],"order": 0,"settings": {"index": {"lifecycle": {"rollover_alias": "m22_sample_30","name": "iscas-ilm-policy"},"routing": {"allocation": {"require": {"hotwarm_type": "hot"}}},"number_of_shards": "6","number_of_replicas": "1","translog": {"durability": "async","sync_interval": "30s","flush_threshold_size": "1024mb"}}},"mappings": {}
}
)
