Description

Currently, we assume that all compensated command are sent out from the same alpha and the compensated results are sent back from different omega to the same alpha. However, when this alpha instance fails, the omega will send the compensated results to another alpha as alpha is stateless. We still need to query the db to keep transaction status consistent.
