Features

  • Excel file support.
  • Table Value Functions: range and tumble for now. Documentation
  • Configurable separators for CSV files.
  • Support for CSV files with no header row.
  • Support for uppercase field names (they get lowercased).

Internals

  • We finally switched to a custom sql parser (copied from vitess) which allowed us to add TVF's and will allow us to add other potential modifications to our SQL dialect.
  • Support for record metadata, including stuff like retracting records. This is important for further work on streaming support.
  • Record serialization, which will make it possible to use disk based key-value state storage.
