>
> While the demander node is in the partition file transmission state it must
> save all cache entries corresponding to the moving partition into a new
> temporary WAL storage. These entries will be applied later one by one on the
> received cache partition file. All asynchronous operations will be enrolled
> to the end of temporary WAL storage during storage reads until it becomes
> fully read. The file-based FIFO approach assumes to be used by this process.
> The new write-ahead-log manager for writing temporary records must support to:
> * Unlimited number of wal-files to store temporary data records;
> * Iterating over stored data records during an asynchronous writer thread
> inserts new records;
> * WAL-per-partiton approach needs to be used;
> * Write operations to temporary WAL storage must have higher priority over
> reading operations;
