YDB CLI changelog

Version 2.8.0

Released on January 12, 2024. To update to version 2.8.0, select the Downloads section.

Features:

  • Added configuration management commands for the cluster ydb admin config and ydb admin volatile-config.

  • Added support for loading PostgreSQL-compatible data types by ydb import file csv|tsv|json command. Only for row-oriented tables.

  • Added support for directory load from an S3-compatible storage in the ydb import s3 command. Currently only available on Linux and Mac OS.

  • Added support for outputting the results of ydb table query execute, ydb yql and ydb scripting yql commands in the Apache Parquet format.

  • In the ydb workload commands, the --executer option has been added, which allows to specify which type of queries to use.

  • Added a column with median benchmark execution time in the statistics table of the ydb workload clickbench command.

  • (Experimental) Added the generic request type to the ydb table query execute command, allowing to perform DDL and DML operations, return with arbitrarily-sized results and support for MVCC. The command uses an experimental API, compatibility is not guaranteed.

  • (Experimental) In the ydb table query explain command, the --collect-diagnostics option has been added to collect query diagnostics and save it to a file. The command uses an experimental API, compatibility is not guaranteed.

Bug fixes:

  • Fixed an error displaying tables in pretty format with Unicode characters.

  • Fixed an error substituting the wrong primary key in the command ydb tools pg-convert.

Version 2.5.0

Released on June 20, 2023. To update to version 2.5.0, select the Downloads section.

Features:

  • For the ydb import file command, a parameter --timeout has been added that specifies the time within which the operation should be performed on the server.
  • Added a progress bar in commands ydb scheme rmdir --recursive and ydb import file.
  • Added the command ydb workload kv run read-rows, which loads the database with requests to read rows using a new experimental API call ReadRows (implemented only in the main branch), which performs faster key reading than select.
  • New parameters --warmup-time, --percentile, --topic have been added to the ydb workload topic, setting the test warm-up time, the percentile in the statistics output and the topic name, respectively.
  • Added the ydb workload tpch command to run the TPC-H benchmark.
  • Added the --ordered flag in the command ydb tools dump, which preserves the order by primary key in tables.

Performance:

  • The data loading speed in the ydb import file command has been increased by adding parallel loading. The number of threads is set by the new parameter --threads.
  • A performance of the ydb import file json command has been increased by reducing the number of data copies.

Version 2.4.0

Released on May 24, 2023. To update to version 2.4.0, select the Downloads section.

Features:

Version 2.3.0

Release date: May 1, 2023. To update to version 2.3.0, select the Downloads section.

Features:

  • Added the interactive mode of query execution. To switch to the interactive mode, run ydb yql without arguments. This mode is experimental: backward compatibility is not guaranteed yet.
  • Added the ydb index rename command for atomic replacement or renaming of a secondary index.
  • Added the ydb workload topic command for generating the load that reads messages from topics and writes messages to topics.
  • Added the --recursive option for the ydb scheme rmdir command. Use it to delete a directory recursively, with all its content.
  • Added support for the topic and coordination node types in the ydb scheme describe command.
  • Added the --commit option for the ydb topic consumer command. Use it to commit messages you have read.
  • Added the --columns option for the ydb import file csv|tsv command. Use it as an alternative to the file header when specifying a column list.
  • Added the --newline-delimited option for the ydb import file csv|tsv command. Use it to make sure that your data is newline-free. This option streamlines import by reading data from several file sections in parallel.

Bug fixes:

  • Fixed the bug that resulted in excessive memory and CPU utilization when executing the ydb import file command.

Version 2.2.0
