-------------------------------------------
Summary: Possible thread starvation due to rebalancing
Key: IGNITE-3073
URL: https://issues.apache.org/jira/browse/IGNITE-3073
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: 1.5.0.final
Reporter: Valentin Kulichenko
Assignee: Valentin Kulichenko
Priority: Critical
Fix For: 1.6
We're currently rebalancing the utility cache in the system pool. This can
cause starvation, for example in this scenario:
# Start several nodes and a cache with indexing configured.
# Continuously load the system with puts.
# Add one more node. It will join and will start processing put requests
immediately.
# For each request, indexing processor will try to get binary metadata and will
block on utility cache rebalance future. This will block all threads in the
system pool.
# Utility cache rebalancing will be scheduled but will never start, because all
threads in system pool are blocked.
I think we should rebalance utility cache synchronously in exchange worker,
like we do with the marshaller cache.
