On commit, after writing oplog entries for buffered operations, a “commitTransaction” oplog entry is written with a new subfield of the command (“o” field) { “prepared” : false } to distinguish from prepared transactions.
{
"ts": Timestamp(1538534630, 10),
"t": NumberLong(1),
"op": "c",
"ns": "admin.$cmd",
// The new commitTransaction command, for unprepared transactions.
"o": { "commitTransaction": 1, "prepared": false },
"lsid": < lsid > ,
"txnNumber": NumberLong("1"),
// Pointing to the previous oplog entry in the transaction.
"prevOpTime": { "ts": Timestamp(1538534630, 2), "t": NumberLong(1) }
}
The IDL format of commitTransaction oplog entry should be updated to include the new field.
