Implement support so Transactions do not need to create visible temporary docs

    XMLWordPrintable

Details

    Description

      Currently to implement Transactions the SDK creates temporary (empty) documents during the execution of a transaction - before it has been committed.
      The documents can "leak" to DCP and non-transactional reads, and hence violate read committed semantics.

      KV needs to provide support for these documents that are created during the running of the transaction, so they are not visible until the transaction is successfully committed.
