T-DIGEST FUNCTIONS
T-Digest Functions# Data Structures#. A T-digest is a data sketch which stores approximate percentile information. The Presto type for this data structure is called tdigest.T-digests can be merged, and for storage and retrieval they can be cast to and from VARBINARY..Functions#
RELEASE 0.207
Release 0.207# General Changes#. Fix a planning issue for queries where correlated references were used in VALUES.. Remove support for legacy JOIN USING behavior.. Change behavior for unnesting an array of row type to produce multiple columns.. Deprecate the reorder_joins session property and the reorder-joins configuration property. They are replaced by the join_reordering_strategy sessionRELEASE 0.60
Release 0.60# JDBC improvements#. The Presto version of the JDBC DatabaseMetaData interface now includes proper implementations of getTables, getSchemas and getCatalogs.. The JDBC driver is now always packaged as a standalone jar without any dependencies. PRESTO | CORPORATE GUIDELINES Guidelines for Participants with Corporate Interests. The goal of the Presto community is to help all participants be successful in using Presto in their environment, and is specifically not for the promotion of any corporate interests including marketing, sales, recruiting,etc.
RELEASE 0.191
Release 0.191# General Changes#. Fix regression that could cause high CPU usage for join queries when dictionary processing for joins is enabled. Fix bit_count() for bits between 33 and 63.. The query.low-memory-killer.enabled config property has been replaced with query.low-memory-killer.policy.Use total-reservation to continue using the previous policy of killing the largest query.RELEASE 0.101
Note. This is a backwards incompatible change with the previous connector SPI. If you have written a connector, you will need to update your code before deploying this release.
