(copied to CRM)
We now have a tunable max batch size for inserts (typically 500). While an insert batch is being inserted, replication of any operations started after the batch is blocked because insert holds open an oplog hole. Normally this is fine, but if the inserts are slow, this can cause overall replication lag; if we could prevent this or detect this (e.g. break up an insert batch when it gets long) we could avoid lag.
