Feature Description

After reading through the two parts of code:

1. org.polypheny.db.adapter.index.CoWHashIndex
2. org.polypheny.db.adapter.index.CowMultiHashIndex

• CoWHashIndex: Implements a hash index for unique keys. It supports basic insertion and deletion operations, as well as transactional operations like commit and rollback, but it deals with the insertion and deletion of individual key-value pairs.

• CowMultiHashIndex: Extends the hash index to support non-unique keys, allowing one key to correspond to multiple values. This class particularly supports batch processing of updates, meaning it can insert or delete multiple key-value pairs simultaneously. This is especially useful for scenarios that require handling multiple update operations within a single transaction.
