Altinity Stable Release for ClickHouse 19.13.7.57

Details of the Altinity Stable Release 19.13.7.57

Description

This is a minor upgrade over the previous release.

Major New Features

  • CREATE TABLE AS TABLE FUNCTION statement that allows to create tables from external data automatically, e.g. from mysql table.
  • COLUMN('regexp') macro function as a generalization of SELECT * queries.

Bug Fixes

  • Fixed security vulnerability in url() function.
  • Fixed security vulnerability related to Zookeeper.
  • Fixed vulnerabilities in compression codecs.
  • Fixed corner case overflows in DoubleDelta codec.

Known Issues

  • ANY INNER|RIGHT|FULL JOIN is deprecated! While we like how it worked before, there are plans to change the behavior completely. We are still discussing with the development team how we can preserve the old behavior. For now, in order to preserve the old behavior and safely upgrade to newer versions in the future one needs to enable any_join_distinct_right_table_keys setting!
  • The setting input_format_defaults_for_omitted_fields is on by default. It enables calculation of complex default expressions for omitted fields in JSONEachRow and CSV* formats. Inserts to Distributed tables need this setting to be the same across the cluster.
    • You need to set input_format_defaults_for_omitted_fields across the cluster before the upgrade if rolling upgrade is performed.
