---------------------------------------
Summary: GridNearAtomicUpdateRequest allocates to much Object[]
Key: IGNITE-2502
URL: https://issues.apache.org/jira/browse/IGNITE-2502
Project: Ignite
Issue Type: Sub-task
Components: cache
Affects Versions: 1.5.0.final
Reporter: Vladimir Ozerov
Assignee: Vladimir Ozerov
Fix For: 1.6
*Problem*
GridNearAtomicUpdateRequest might create up to 4 ArrayList's. Initially they
are empty. When the very first element is added, ArrayList is extended to hold
10 objects (new Object[]). Put in ATOMIC cache almost all operations are
performed on a single key.
As a result 90% of array is not used.
*Proposed solution*
We know in advance how many keys participate in operation. Let's use min(10,
keyCount) as initial array list size. This will make allocation more accurate.
