------------------------------------------
Summary: Get rid of synchronous cache destroying in multiple
caches group.
Key: IGNITE-12572
URL: https://issues.apache.org/jira/browse/IGNITE-12572
Project: Ignite
Issue Type: Improvement
Affects Versions: 2.7.6
Reporter: Alexey Scherbakov
Fix For: 2.9
Current implementation of destroying a cache belonging to multiple caches group
is done synchronously in exchange worker and blocks exchange events processing
[1].
This has negative impact on grid availability if topology is changed during
this process.
Proposed solution: make cache destroying asynchronous, similar to partition
eviction. Same mechanics can be reused for clearing partition of destroyed
cache data.
Special attention should be given to the case then cache is recreated while
being destroyed.
The idea is to continue clearing of old data asynchronously and insert new data
using new cache generation. This can be achieved for example by implementing
unique key prefixes for each cache generation.
