Ilya Lantukh commented on IGNITE-2948:
--------------------------------------
Possible further optimizations:
1. GridCachePartitionTopologyImpl - get rid of RW lock, use volatile
reads/writes.
2. Adjust parameters of internal CHM in new GridCacheConcurrentMapImpl.
Fixed most of the tests, working on the following problems now:
1. Occasional hang-ups in tests that involve constant topology changes.
2. Sometimes GridCacheAdapter tries to create local partition that shouldn't
belong to current node, resulting in GridDhtInvalidPartitionException.
> Optimize usage of GridCacheConcurrentMap
