Open Source Presto Releases & Features ⬆️

Great start of September with release 0.261! Key features from this release 

Prometheus Connector Support
The Prometheus connector allows reading Prometheus metrics data as tables in Presto. Great contribution from fgwang7w!

Iceberg data files are now written to paths defined by Iceberg’s LocationProvider
This feature allows Iceberg to write data to a location different from the hard-coded table’s root location. Iceberg connector can write data files to paths defined by Iceberg’s LocationProvider. This is especially important for cloud object storage users who leverage Iceberg’s ObjectStorageLocationProvider to write data to hashed file paths to avoid throttling. Shout out to jackye1995 for contribution!

Improve Decimal Aggregation Performance
This change improves performance of SUM() and AVG() aggregate functions when used with DECIMAL type. Shout out to pettyjamesm for contribution!
