Would we need to have a schema definition attached to the program?

Features:

  • Dump parquet files in batch, with a batch size.
  • Provide a structured format for filenames. Example: {table_name}/{blocktime:%Y-%m-%d}/[start-blocknum]_[end-blocknum].parquet
  • The blocktime can be plucked from the Clock, and start and end blocknums being batch ranges.
  • Table name can be extracted from the objects.

Questions:

  • Would the proto model be DatabaseChanges? Would it expect only create operations?
