Over the past month, new features have been added across a broad span of the Iceberg project. In this monthly roundup, we cover a few of these big additions and what it means for Iceberg users.
Starting with Flink, the new FLIP-27 reader is now supported in SQL. This means you can now enable FLIP-27 using an opt-in configuration.
Much progress has been made around the implementation for the new branching and tagging specification. New additions from the Iceberg community have enabled performing snapshot operations using a branch reference instead of a snapshot ID.
Another recently added feature is support for table scan reporting. Metrics can now be collected during table scans to provide rich insights. The initial version only collects some basic metrics but provides a framework for the community to build more advanced metrics and easily include them in scan reports.
Some big news around the Iceberg Spark runtime is the addition of a new function catalog. This makes it possible to use functions like
iceberg_version() without having to register it as a UDF. Functions like
truncate have also been added to the function catalog and are available to use in Spark with any Iceberg catalog.
The community is continuing to see rapid progress around the new
pyiceberg library and the latest additions include a new CLI. The CLI lets you connect to an Iceberg catalog and perform various catalog operations like listing, creating, and renaming Iceberg tables. As we head full speed towards the first official release of the new
pyiceberg library, many features will be additionally exposed through the CLI interface, making it easier than ever to manage tables in an Iceberg catalog!
New Engine Support
Earlier this month Bodo, a next-generation SQL and Python data processing platform, announced an alpha version of a Bodo-Iceberg connector as well as a roadmap for fully supporting Iceberg’s growing set of features. The Bodo platform is capable of massive parallel I/O and compute and pairs very well with the design of Iceberg tables.
