Enum InlineFormat

Source 
pub enum InlineFormat {
    Header,
    RawMeta,
    RawData,
    StbData,
}
Expand description

Inlined data format in backup file.

Variants§

§

Header

Only located at the exactly header of a file, contains basic information describing the data included.

  1. database name
  2. database schema
  3. single table or not.
§

RawMeta

Raw meta message from TMQ, which could be write back to a TDengine cluster seamlessly.

§

RawData

Raw data message from TMQ, contains data block of a child table or common table.

§

StbData

For stable data not use TMQ, contains STable schema and table name - tags entry map.

This type of data will be built from legacy whole backup strategy.
