Open Source Presto Releases & Features ⬆️

We had a great start to the month with release 0.263, the top features of the month are: 

Add support to perform heapDump on exceeded memory limit failures which supports an ability to trigger a heap dump in exceeded_memory_limit failure cases. This will greatly improve debugging experiences around query OOMs. Shout out to Arjun Gupta pgupta2 for contribution!

Implement key-based sampling in the planner with this feature enabled, Presto traverses the plan for the query and samples the first integer or string key found. This helps users to get a sense of the results for queries which are running on large datasets that keep failing/running for a long time/timing out. Thanks, Sreeni Viswanadha kaikalur for the contribution!

Thanks so much for your continued support! We hope you enjoyed these updates. See you in the Slack channel. prestodb.slack.com
