> If the transaction is aborted between openTxn and addPartitions and data has
> been written on the table the transaction manager will think it's an empty
> transaction and no cleaning will be done.
> This is currently an issue in the streaming API and in micromanaged tables.
> As proposed by [~ekoifman] this can be solved by:
> * Writing an entry with a special marker to TXN_COMPONENTS at openTxn and
> when addPartitions is called remove this entry from TXN_COMPONENTS and add
> the corresponding partition entry to TXN_COMPONENTS.
> * If the cleaner finds and entry with a special marker in TXN_COMPONENTS that
> specifies that a transaction was opened and it was aborted it must generate
> jobs for the worker for every possible partition available.
