# Set a timeout on metrics data. After the timeout has expired, the metrics data will automatically be deleted.
##### 数据清理开关,默认开启
enableDataKeeperExecutor: ${SW_CORE_ENABLE_DATA_KEEPER_EXECUTOR:true} # Turn it off then automatically metrics data delete will be close
##### 数据清理定时器,默认5分钟
dataKeeperExecutePeriod: ${SW_CORE_DATA_KEEPER_EXECUTE_PERIOD:5} # How often the data keeper executor runs periodically, unit is minute
##### 明细记录有效期,默认3天
recordDataTTL: ${SW_CORE_RECORD_DATA_TTL:3} # Unit is day

l1FlushPeriod: ${SW_CORE_L1_AGGREGATION_FLUSH_PERIOD:500}
# The threshold of session time. Unit is ms. Default value is 70s.
##### 会话时间阈值,默认70秒

# Extra model column are the column defined by in the codes, These columns of model are not required logically in aggregation or further
query,
# and it will cause more load for memory, network of OAP and storage.
# But, being activated, user could see the name in the storage entities, which make users easier to use 3rd party tool, such as Kibana->
ES, to query the data by themselves.
##### 代码中定义的额外模型列,这些模型列在聚合或查询时不需要,会加重负载。但激活后,用户可以看到名称,更容易自行查询数据。
