Set Config Action
Request
GET /api/_set_config
Description
用于动态设置 FE 的参数。该命令等同于通过 ADMIN SET FRONTEND CONFIG
命令。但该命令仅会设置对应 FE 节点的配置。并且不会自动转发 MasterOnly
配置项给 Master FE 节点。
Path parameters
无
Query parameters
confkey1=confvalue1
指定要设置的配置名称,其值为要修改的配置值。
persist
是否要将修改的配置持久化。默认为 false,即不持久化。如果为 true,这修改后的配置项会写入
fe_custom.conf
文件中,并在 FE 重启后仍会生效。reset_persist
是否要清空原来的持久化配置,只在 persist 参数为 true 时生效。为了兼容原来的版本,reset_persist 默认为 true。
如果 persist 设为 true,不设置 reset_persist 或 reset_persist 为 true,将先清空fe_custom.conf
文件中的配置再将本次修改的配置写入fe_custom.conf
;
如果 persist 设为 true,reset_persist 为 false,本次修改的配置项将会增量添加到fe_custom.conf
。
Request body
无
Response
{
"msg": "success",
"code": 0,
"data": {
"set": {
"key": "value"
},
"err": [
{
"config_name": "",
"config_value": "",
"err_info": ""
}
],
"persist":""
},
"count": 0
}
set
字段表示设置成功的配置。err
字段表示设置失败的配置。 persist
字段表示持久化信息。
Examples
设置
storage_min_left_capacity_bytes
、replica_ack_policy
和agent_task_resend_wait_time_ms
三个配置的值。GET /api/_set_config?storage_min_left_capacity_bytes=1024&replica_ack_policy=SIMPLE_MAJORITY&agent_task_resend_wait_time_ms=true Response: { "msg": "success", "code": 0, "data": { "set": { "storage_min_left_capacity_bytes": "1024" }, "err": [ { "config_name": "replica_ack_policy", "config_value": "SIMPLE_MAJORITY", "err_info": "Not support dynamic modification." }, { "config_name": "agent_task_resend_wait_time_ms", "config_value": "true", "err_info": "Unsupported configuration value type." } ], "persist": "" }, "count": 0 } storage_min_left_capacity_bytes 设置成功; replica_ack_policy 设置失败,原因是该配置项不支持动态修改; agent_task_resend_wait_time_ms 设置失败,因为该配置项类型为long, 设置boolean类型失败。
设置
max_bytes_per_broker_scanner
并持久化GET /api/_set_config?max_bytes_per_broker_scanner=21474836480&persist=true&reset_persist=false Response: { "msg": "success", "code": 0, "data": { "set": { "max_bytes_per_broker_scanner": "21474836480" }, "err": [], "persist": "ok" }, "count": 0 }
fe/conf 目录生成fe_custom.conf:
#THIS IS AN AUTO GENERATED CONFIG FILE. #You can modify this file manually, and the configurations in this file #will overwrite the configurations in fe.conf #Wed Jul 28 12:43:14 CST 2021 max_bytes_per_broker_scanner=21474836480
