> To support ACID replication, we will be introducing a per table write Id 
> which will replace the transaction id in the primary key for each row in a 
> ACID table.
> The current primary key is determined via 
>  <original transaction id, bucketid , rowid>
> which will move to 
>  <original write id, bucketid, rowid>
> For each table modified by the given transaction will have a table level 
> write ID allocated and a persisted map of global txn id -> to table -> write 
> id for that table has to be maintained to allow Snapshot isolation.
> Readers should use the combination of ValidTxnList and 
> ValidWriteIdList(Table) for snapshot isolation.
