      Adding metrics around the size of transactions could help us determine what use cases to optimize for. Metrics for the last run transaction:

      1. Number of operations in the transaction
      2. Total size of transaction statements in oplog
      3. Write Concern

      There will be a new serverStatus section transactions.lastCommittedTransaction:

      {
    "operationCount" : NumberLong(1),
    "oplogOperationBytes" : NumberLong(151),
    "writeConcern": {
        "w" : 1,
        "wtimeout" : 0
    }
}
