----------------------------------------
Summary: Assertion error in ATOMIC cachce for invokeAll and cache
store
Key: IGNITE-2645
URL: https://issues.apache.org/jira/browse/IGNITE-2645
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: ignite-1.4
Reporter: Alexey Goncharuk
Assertion happens under the following conditions:
* Cache is empty
* Cache store contains non-null values for some keys
* invokeAll is invoked for those keys
Update version is generated when update request reaches the primary node. Then,
we need to read-through stored values (the cache is empty) and pass them to
transformers. Since read-through changes entry version, subsequent update fails
with an assertion because read-through version is generated later than update
version.
The scenario when a read-through is implemented via a separate loop with
innerGet() is possible only with invokeAll() because this is the only multi-key
cache operation that requires the previous entry value.
