Andrey Mashenkov created IGNITE-14769:
-----------------------------------------

             Summary: Key hash calculation.
                 Key: IGNITE-14769
                 URL: https://issues.apache.org/jira/browse/IGNITE-14769
             Project: Ignite
          Issue Type: Improvement
            Reporter: Andrey Mashenkov


There are next possible ways for cache calculation.
 # Update hash on every write method call as it works for now.
 # Calculate hash for serialized column values, but excluding a null-map) (hash of byte[])
 # Calculate for all key chunk (hash of byte[]) - all columns including a null-map.

Let's choose and implement the best way and along with better hash function.
