Apache Drill 0.7.0 Key Notes and Limitations

- -
    -
  • The current release supports in-memory and beyond-memory execution. However, you must disable memory-intensive hash aggregate and hash join operations to leverage this functionality.
    • -
  • While the Drill execution engine supports dynamic schema changes during the course of a query, some operators have yet to implement support for this behavior, such as Sort. Other operations, such as streaming aggregate, may have partial support that leads to unexpected results.
