Description
Implement changes to support eviction of prepared and committed prepared updates. Since prepare and commit APIs are already implemented, this ticket is meant to:
- when prepare is called, the current committed record needs to be written to the history store.
- make sure that prepared and committed updates are formatted correctly in the cells of the data files.
- ensure that prepared and committed cells that are read from the data files create the appropriate update records.
- when abort is called on a prepared record, the corresponding commit record in the history store must be removed.
