Chris M. Hostetter commented on SOLR-16954:
-------------------------------------------
Jan: changing from 75% to 99% isn't eliminating the failure, just changing the
probabilities that they happen.
The Memory Circuit Breaker needs to be completely removed from the config to
prevent these false failures.

> Circuit breaker for update requests

> Key: SOLR-16954
> URL: https://issues.apache.org/jira/browse/SOLR-16954
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Circuit Breakers
> Reporter: Jan Høydahl
> Assignee: Jan Høydahl
> Priority: Major
> Fix For: 9.4
>
> Time Spent: 50m
> Remaining Estimate: 0h
>
> Provide a way to utilize any circuit breaker for update requests.
> The idea is that any CircuitBreaker plugin should be able to register for
> SEARCH and/or UPDATE request types. The CB registry will keep track of these
> individually and provide methods to poll whether a CB has tripped for the
> given request type.
