10.3. Release 0.98

Array, Map, and Row Types

The memory representation of these types is now VariableWidthBlockEncoding instead of JSON.

Note

This is a backwards incompatible change with the previous representation, so if you have written a connector or function, you will need to update your code before deploying this release.

Hive Changes

  • Fix handling of ORC files with corrupt checkpoints.

SPI Changes

  • Rename Index to ConnectorIndex.

Note

This is a backwards incompatible change, so if you have written a connector that uses Index, you will need to update your code before deploying this release.

General Changes

  • Fix bug in UNNEST when output is unreferenced or partially referenced.
  • Make max() and min() functions work on all orderable types.
  • Optimize memory allocation in max_by() and other places that Block is used.
