Presto Community on the Move

Open Source Presto Releases & Features 

It’s been an exciting month with three new releases: 0.2580.259 and 0.260
Some great community-requested features made it in 

hudi image newsletter

Add support for partition schema evolution for HUDI tables

Partition schema evolution support is crucial when users introduce new columns in the middle of the table, otherwise attempting to access one of the partitions with the older schema results in an error. This now works with Hudi tables. Shout out to imjalpreet for the contribution

iceberg newsletter

Add ORC support for iceberg connector (0.258)
Iceberg data files can be stored in either Parquet or ORC format. Iceberg connector can now be used to query the data stored in ORC format in addition to Parquet format. Shout out to junyi1313 for the contribution.

Introduce query limits at the resource group level (0.259)

Resource groups place limits on resource usage, and can now enforce queueing policies on queries. Users can specify query limits in terms of cpu time, total memory and execution time at the resource group level. Great contribution from kyleCampbel1
