Dear community, This mail is regarding parallel insert and update. Currently we are not supporting concurrent insert (or load data) and update because it may cause data inconsistency or incorrect result.
Now Carbon blocks update operation when insert operation is in progress by throwing out concurrent operation exception directly. If there is an executing insert operation that is very time consuming, then update operation has to wait and sometimes this waiting time is very long. To come out with this problem, we are planning to support parallel insert and update. And here I have proposed one of the solutions to implement this feature. This is the design document: Parallel_Insert_and_Update.pdf <http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/file/t495/Parallel_Insert_and_Update.pdf> Please go through this solution document and provide your input if this approach is okay or any drawback is there.
