12.134. Release 0.113

The ORC reader in the Hive connector is broken in this release.

The cluster resource manager announced in Release 0.103 is now enabled by default.You can disable it with the flag.Memory limits can now be configured via query.max-memory which controls the total distributedmemory a query may use and query.max-memory-per-node which limits the amountof memory a query may use on any one node. On each worker, theresources.reserved-system-memory config property controls how much memory is reservedfor internal Presto data structures and temporary allocations.

This type safety extends to the where propertiescan be validated and converted to any Java type usingSessionPropertyMetadata. For an example, see HiveSessionProperties.

Note

• Allow using any type with value window functions first_value(),, nth_value(), and .
• Add function.
• Add url_encode() and functions.
• concat() now allows arbitrary number of arguments.
• Fix handling of literal NULL in .
• Fix an issue that caused some specific queries to fail in planning.

• Fix the Hive metadata cache to properly handle negative responses.This makes the background refresh work properly by clearing the cachedmetadata entries when an object is dropped outside of Presto.In particular, this fixes the common case where a table is dropped usingHive but Presto thinks it still exists.
• Fix metastore socket leak when SOCKS connect fails.

Note

This is a backwards incompatible change with the previous connector SPI.If you have written a connector that uses structural types, you will needto update your code to the new APIs.
