    Description

      Currently data is hash-partitioned to all partitions of a dataset.

      While this yields a good distribution of data, it is not ideal for rebalancing (as too much data gets moved) or reingestion from KV (as too much data needs to be re-read).

      We need to investigate what changes are needed to distribute the data of a dataset in a way that

      • avoids moving too much data and that
      • allows for different distribution strategies for different datasets.
