Ivan Fedotov commented on IGNITE-10376:
---------------------------------------
[~rkondakov], Thank you for the explanation. I investigated this issue and it
seems to me that the problem relates to IGNITE-9830 which is about race in
binary metadata registration. Because in
{{CacheObjectBinaryProcessorImpl.metadata(CacheObjectBinaryProcessorImpl.java:685)}}
was implemented awaiting for schema update, sometimes it can lead to the
deadlock during partition map exchange: PME waits for finishing transactions
and updating metadata waits for finishing PME. I will try to move updating
metadata to the system thread pool (PME proceeds in the striped pool) - it can
treat deadlock.
