2023 Changelog

ClickHouse release v23.5.4.25-stable (190f962abc) FIXME as compared to v23.5.3.24-stable (76f54616d3)

Improvement

  • Backported in #51235: Improve the progress bar for file/s3/hdfs/url table functions by using chunk size from source data and using incremental total size counting in each thread. Fix the progress bar for *Cluster functions. This closes #47250. #51088 (Kruglov Pavel).
  • Backported in #51255: Disable cache setting do_not_evict_index_and_mark_files (Was enabled in 23.5). #51222 (Kseniia Sumarokova).

Build/Testing/Packaging Improvement

  • Backported in #51531: Split huge RUN in Dockerfile into smaller conditional. Install the necessary tools on demand in the same RUN layer, and remove them after that. Upgrade the OS only once at the beginning. Use a modern way to check the signed repository. Downgrade the base repo to ubuntu:20.04 to address the issues on older docker versions. Upgrade golang version to address golang vulnerabilities. #51504 (Mikhail f. Shiryaev).
  • Backported in #51572: This a follow-up for #51504, the cleanup was lost during refactoring. #51564 (Mikhail f. Shiryaev).
