Method Detail

• mergeAndCommit

  void mergeAndCommit(KVTransaction src,
                    KVTransaction dst,
                    Date lastActiveTime)

  Merge data from the source database being migrated away from into the destination database being migrated to.

  This method should commit() both transactions before returning; src should be committed before dst.

  If an exception is thrown, rollback() will be invoked on both transactions (a rollback() on an already-commit()'ed transaction does nothing).

  Parameters:

  src - read-only view into the database being migrated away from

  dst - read-write transaction open on the database being migrated to

  lastActiveTime - time that dst was last active, or null if never

  Throws:

  RuntimeException - if the merge or either commit() fails
