Expand description

Fields§

§table_name: String

表名

§ttl_seconds: Option<i32>

数据生命周期,单位为秒。 默认为 -1 表示永不过期。最低 86400 秒(1 天)

§allow_update_attributes: Option<bool>

是否允许更新时间线属性列

§meta_ttl_seconds: Option<i32>

时间线生命周期,单位为秒。取值必须大于等于 604800 秒(即 7 天)或者必须为 -1(数据永不过期)。

§analytical_store: Option<TimeseriesAnalyticalStore>

分析存储信息。默认为 None 表示不创建分析存储

§lastpoint_indexes: HashSet<String>

lastpoint 索引

§timeseries_keys: Vec<String>

自定义时间线主键。留空则表示采用默认的 _m_name_data_source_tags

§field_primary_keys: Vec<PrimaryKeySchema>

作为主键的数据字段,支持配置多个。 当实际业务中存在时间线标识和时间点相同,但是时序数据不同的数据存储需求时,您可以通过为时序表添加作为主键的数据字段来实现。
