Q. Why is my Scale/Pause/Resume taking so long?
53
53
54
-
A. A variety of factors can influence the time for compute management operations. A common case for long running operations is transactional rollback. When a scale or pause operation is initiated, all incoming sessions are blocked and queries are drained. In order to leave the system in a stable state, transactions must be rolled back before an operation can commence. The greater the number and larger the log size of transactions, the longer the operation will be stalled restoring the system to a stable state.
