I'm having issues with the target collection staying up-to-date with indexing
from the source collection using CDCR.
This is what I'm getting back in terms of OPS:
curl -s 'solr2-a:8080/solr/mycollection/cdcr?action=OPS' | jq .
{
"responseHeader": {
"status": 0,
"QTime": 0
},
"operationsPerSecond": [
"zook01,zook02,zook03/solr",
[
"mycollection",
[
"all",
49.10140553500938,
"adds",
10.27612635309587,
"deletes",
38.82527896994054
]
]
]
}
The source and target collections are in separate data centers.
Doing a network test between the leader node in the source data center and the
ZooKeeper nodes in the target data center
show decent enough network performance: ~181 Mbit/s
I've tried playing around with the "batchSize" value (128, 512, 728, 1000,
2000, 2500) and they've haven't made much of a difference.
Any suggestions on potential settings to tune to improve the performance?
Thanks

Here's some relevant log lines from the source data center's leader:
