My setup is a 3 shard index with 20GB per shard. I am migrating from a
master/slave replication to TLOG replicas using Solr 7.1.
In my use case I have to recreate my index from scratch each day. I have a
heterogeneous setup with a high powered indexer and lesser searcher that answer
queries.
My method it to create a new collection with a single TLOG instance and then
build the data. When complete I use ADDREPLICA to create the replicas on the
searcher instances.
My issue is that the replication after the ADDREPLICA seems to be limited to
about 100Mbits per second. I am on a 1Gbit network and I am able to rsync or
scp at full speed. This causes excess delays and it is a real problem. I've
looked for what is throttling the replication, but I have not found anything
that makes any difference. I've tried
<requestHandler name="/replication" class="solr.ReplicationHandler">
<lst name="invariants">
<str name="maxWriteMBPerSec">1000</str>
</lst>
</requestHandler>
That did not change anything.
Is there a config option that I have not found to control this? I've looked in
the source code, but have not found anything there either.
Thanks in advance if anyone could help point me in the correct direction in
either config options or where this might be in the source.
