v0.7.1

We are excited to announce the release of two new extensions: Delta Lake and Iceberg. The Delta extension allows seamless scanning and copying from Delta Lake tables, while the Iceberg extension provides the same functionality for Apache Iceberg tables.

• The ability to attach to a specific schema in a relational database.
• Support for ADD/DROP PROPERTY IF [NOT] EXISTS commands.
• A new list_has_all function for enhanced list operations.
• Experimental support for Android armv8a platform.

Hope you enjoy the new release!

v0.7.0

Key highlights of this release

There have been some key performance improvements in this release:

• New and much faster recursive path finding algorithms that implement relationship patterns
  with the Kleene star [*].
• Data spilling to disk during copy which enables copying very large graphs on machines with
  limited RAM.
• Zone maps which enable much faster scans of node/rel properties when there is
  a filter on numeric properties.

From the usability perspective, we have the following improvements:

• CSV auto detection to automatically detect several CSV configurations during data ingest.
• Improved UX during CSV import that can report to users about skipping erroneous CSV lines.
• New JSON data type that you can use to store JSON blobs as node/relationship properties.
• New official Golang API so that you can build applications on top of Kùzu using Go!
