Database transactions across different domains
Abstract:
The subject technology sends a first statement to an execution node for executing the first statement on first storage using micro-partitions. The subject technology sends a second statement to the execution node for executing the second statement on linearizable storage. The subject technology sends a request to prepare a commit of a cross domain transaction associated with the first statement and the second statement. The subject technology generates a new version of a set of tables that were modified by the cross domain transaction and updating first metadata in a metadata database to indicate the new version. The subject technology finalizes the commit of the cross domain transaction and updates second metadata that the cross domain transaction has been committed.
