Interface DataSourceStatus

The last error encountered. May be absent after application restart.

An enumerated value representing the overall current state of the data source.

The UNIX epoch timestamp in milliseconds that the value of State most recently changed.

The meaning of this depends on the current state: For 'INITIALIZING', it is the time that the datasource started attempting to retrieve data.

For 'VALID', it is the time that the data source most recently entered a valid state, after previously having been 'INITIALIZING' or an invalid state such as 'INTERRUPTED'.

• For 'INTERRUPTED', it is the time that the data source most recently entered an error state, after previously having been 'VALID'.

For 'CLOSED', it is the time that the data source encountered an unrecoverable error or that the datasource was explicitly closed.
