November 3, 2022

This release removes read & write units from pricing (see the pricing page for details), updates the ClickHouse version to 22.10, adds support for higher vertical scaling for self-service customers, and improves reliability through better defaults.

General changes

  • Removed read/write units from the pricing model

Configuration changes

  • The settings allow_suspicious_low_cardinality_types, allow_suspicious_fixed_string_types and allow_suspicious_codecs (default is false) cannot be changed by users anymore for stability reasons.

Console changes

  • Increased the self-service maximum for vertical scaling to 720GB memory for paying customers

  • Introduced waitlists for GCP and Azure in the service creation dialog
  • Improved error handling during file upload
  • Improved workflows for billing administration

ClickHouse 22.10 version upgrade

  • Improved merges on top of object stores by relaxing the "too many parts" threshold in the presence of many large parts (at least 10 GiB). This enables up to petabytes of data in a single partition of a single table.
  • Improved control over merging with the min_age_to_force_merge_seconds setting, to merge after a certain time threshold.
  • Added MySQL-compatible syntax to reset settings SET setting_name = DEFAULT.
  • Added functions for Morton curve encoding, Java integer hashing, and random number generation.
  • See the detailed 22.10 changelog for the complete list of changes.

October 25, 2022

This release significantly lowers compute consumption for small workloads, lowers compute pricing (see pricing page for details), improves stability through better defaults, and enhances the Billing and Usage views in the ClickHouse Cloud console.

General changes

  • Reduced minimum service memory allocation to 24G
  • Reduced service idle timeout from 30 minutes to 5 minutes

Configuration changes

  • Reduced max_parts_in_total from 100k to 10k. The default value of the max_parts_in_total setting for MergeTree tables has been lowered from 100,000 to 10,000. The reason for this change is that we observed that a large number of data parts is likely to cause a slow startup time of services in the cloud. A large number of parts usually indicates a choice of too granular partition key, which is typically done accidentally and should be avoided. The change of default will allow the detection of these cases earlier.

Console changes

  • Enhanced credit usage details in the Billing view for trial users
  • Improved tooltips and help text, and added a link to the pricing page in the Usage view
  • Improved workflow when switching options for IP filtering
  • Added resend email confirmation button to the cloud console
