  • Presto 0.193 version is generally available. Detailed notes about the 0.193 release are available as a blog post at Introducing Presto 0.193 in QDS.

  • The Qubole Presto Server Bootstrap is an alternative to the Node Bootstrap Script to install external jars such as presto-udfs before the Presto Server is started. This prevents the additional restart of the Presto Server that happens when you install such jars through the Node Bootstrap Script which causes query failures during the node startup. It is only supported in Presto 0.180 and later versions. Disabled

  • Qubole Presto now supports providing full access to the S3 bucket owner for files written to the bucket by other users. Disabled

  • A new FastPath for queries executed by the QDS Drivers. The FastPath minimizes the QDS level time for Presto queries. It is only supported on Presto 0.180. With the Presto FastPath, the overall command latencies within QDS should come down to around 1.5 seconds when the cluster is active. Beta, Via Support

  • The file-based authentication feature has been enhanced to accept only the hashed passwords for each user. Earlier, the plain passwords were accepted and stored as-is on the cluster which posed a security threat. MD5, SHA1, Unix Crypt, and BCrypt hashed passwords are supported. Qubole recommends using MD5 and BCrypt as SHA1 and Unix Crypt are less secure. Learn more.


Data Analytics

  • Partition columns are now marked distinctly on the Analyze page’s Tables tab.

  • You can now view and edit Hive commands greater than 126KB (which were earlier uploaded to Amazon S3) from the UI. Beta, Via Support, Disabled

    Learn more.

Data Engineering

  • For Workflow commands, you can now download subcommand logs as well as results from both the UI and the API. This allows you to get logs and results for subcommands that were run even if the command failed as a whole. Beta, Via Support, Disabled
