- Thread-topic: How to batch modify large amount of entries without increasing replication latency
We are currently using the following:
standard syncprov overlay configuration below
1 master and 3 replicas
each on 15k RAID 10.
Problem is batch modifications (perl ldapmod) consisting of modifying a large number of entries ( > 50k ) will cause major replication delays after a few hours.
The entry updates tend to be small eg adding a new non-indexed attribute and we throttle down the update to only 3 entries per second.
What is the recommended way to batch modify large amounts of entries without taking the directory (master or replica) offline.
Furthermore what is the expected replication throughput eg mods/sec that will sustain no replication delay.
Any and all advice greatly appreciated.

syncprov-checkpoint 50 10
