10 June 2024 - v4.14.1

ClickHouse upgrade to v23.8.10.43 LTS, improved ingest reliability

Notable New Features

  • ClickHouse upgrade to v23.8.10.43 LTS
    • Supports parameterized views, query caching, and other features listed in our v4.14 Upgrade Guide.
  • Improved Ingest Reliability
    • We've included DNS fixes and Traefik improvements.
  • Multi-Cloud Credentials
    • Connect to different cloud accounts in Google Cloud, AWS, Azure, and Linode by defining sets of credentials. Currently, this can help alleviate problems with cloud storage rate limits. It also paves the way for more features based on this flexibility.
