Trey Cahill commented on SOLR-8955:
-----------------------------------
I uploaded a patch that will enable throttling for all requests, which is
configurable (as per [~gpendleb] request), instead of throttling for each
client by setting the parameter "globalthrottling=true".
There's a few thing's that I'm not sure about in creating the patch:
1) Is having the parameter "globalthrottling" the best way to set/configure
throttling?
2) Is this the best way to throttle for all requests to a node?
3) The best way to test this; currently, the patch uses test cases that started
out as copies of the testRateLimitedReplication().
> ReplicationHandler should throttle across all requests instead of for each
> client

> SOLR-6485 added the ability to throttle the speed of replication but the
> implementation rate limits each request. So e.g. the maxWriteMBPerSec is 1
> and 5 slaves request full replication then the effective transfer rate from
> the master is 5 MB/second which is not what is often desired.
> I propose to make the rate limit global (across all replication requests)
> instead.
