Abstract
An analytics tool of a journal-based multi-data-store database obtains respective rejection cause descriptors for a set of transactions rejected by the journal manager of the database due to read-write conflicts. A particular rejection cause descriptor indicates a query predicate used for a read set of a transaction request which was rejected by a journal manager of the database due to a read-write conflict between the read set and a previously-committed transaction. The analytics tool prepares a database contention analysis using the rejection cause descriptors, and transmits the analysis to a client.
