--------------------------------------
Summary: Enhance row level conlict detection to reduce client
memory footprint.
Key: OMID-131
URL: https://issues.apache.org/jira/browse/OMID-131
Project: Apache Omid
Issue Type: Improvement
Reporter: Yonatan Gottesman
Assignee: Yonatan Gottesman
Currently even if omid is working in row level conflict detection, all the
cells are kept by the client until after commit for writing shadow cells or
removing them after abort.
Instead the client should store only the rows or only the family.
If we choose to store only the row, the client memory footprint will be
smaller, but if a region server wants to query a shadow cell for a cell it
might have to query a different region.
On the other hand client can store the famelies of a writeset. This will have a
bigger footprint if we have lots of families but if a region queries a shadow
cell it will be on the same region.
