public virtual Task<Operation> ImportUserEvents(ImportUserEventsRequest request, ServerCallContext context)
Bulk import of user events. Request processing might be
synchronous. Events that already exist are skipped.
Use this method for backfilling historical user events.
Operation.response is of type ImportResponse. Note that it is
possible for a subset of the items to be successfully inserted.
Operation.metadata is of type ImportMetadata.
public virtual Task<Operation> PurgeUserEvents(PurgeUserEventsRequest request, ServerCallContext context)
Deletes permanently all user events specified by the filter provided.
Depending on the number of events specified by the filter, this operation
could take hours or days to complete. To test a filter, use the list
command first.
