Adding metrics around the size of transactions could help us determine what use cases to optimize for. Metrics for the last run transaction:
- Number of operations in the transaction
- Total size of transaction statements in oplog
- Write Concern
There will be a new serverStatus section transactions.lastCommittedTransaction:
{ "operationCount" : NumberLong(1), "oplogOperationBytes" : NumberLong(151), "writeConcern": { "w" : 1, "wtimeout" : 0 } }
