Engineering Ticket Description:
Doing point queries on the ts field is slow in the oplog because the oplog does not have any indexes. WT has a hack that allows it to do binary search on the ts field but is only enabled when the query predicate has top level $gt/$gte.
This is needed by retryable writes in order to do fast lookup on oplog entries when traversing through the write history within a transaction.
