Guys, this is what we have discuss to write the data directly to HBase when
creating an index for a non-empty table.

> Today, when creating an index table for a non empty data table. The writes
> are performed using the transaction api and both consumes client side memory,
> for storing the writeset, and checks for conflict analysis upon commit. This
> is redundant and can be replaced by direct write to HBase. For this reason, a
> new function in the transaction abstraction layer should be added that writes
> directly to HBase at the Tephra's case and adds shadow cells with the fence
> id at the Omid case.
