> *Goals:*
> *1) Implement a “Transaction Manager” with optimistic concurrency to provide
> within a table transaction / versioning.* (interfaces should also be flexible
> enough to support across table transactions)
> *2) Support time travel in carbonData.*
> *3) Decouple and clean up segment interfaces.* (which should also help in
> supporting segment concepts to other open format under carbondata metadata
> service)
