> In multi-active mode, multiple participants will be reading/writing to MySQL
> table. We want to make sure each participant acts on the table in a manner
> that takes into account that the state may have changed while the
> MultiActiveLeaseArbiter is processing the result of a READ. This PR adds unit
> tests that validate SQL Insertion statements are conditional upon the state
> of the particular row corresponding to the flow action event being unchanged
> from the read made by this participant.
