Hi Olo, DataFusion is based on the Arrow model and thus all its data is read only; In order to update data a new copy must be made.
I guess you could call this a version of MVCC. People often use DataFusion to operate on data in files stored in formats such as Parquet which are similarly read optimize, or their own data sources which provides data in record batches Hope that helps, Andrew On Tue, Jan 10, 2023 at 11:08 PM Olo Sawyerr <[email protected]> wrote: > Hi there. > > Does DataFusion have any MVCC capabilities? > > Regards, > Olo > > Sent from Outlook for iOS <https://aka.ms/o0ukef> >
