Version 0.2​

Frontend Improvements:

  • Optimized interaction details and fixed link errors

Mirror Engine Enhancements:

  • Optimized dependency management, reducing deployment package size by 70% to only 96MB
  • Enhanced JDK detection to recognize x64 and aarch64 environments on Linux/Mac systems for more accurate JDK identification, effectively improving engine startup speed to just 3 seconds
  • Optimized data source download with dynamic package support to improve download success rates
  • Unified cache storage paths - all caches now stored in the cache directory for cleaner local directory structure
  • Optimized data table schema loading process by removing foreign key loading, improving loading speed and saving database resources

Connector Updates:

  • Sybase: Removed endianness options from data source configuration, now auto-detected
  • Oracle:
    • Fixed unsupported log parsing configuration in CDC plugin, changed to fixed log miner
    • Added local disk staging for transactions exceeding 10,000 events to prevent excessive engine memory consumption during large transactions

Version 0.3​

Product Rebranding:

  • Product name changed to ChPulse to avoid confusion with ClickHouse's official data integration service ClickPipes

Frontend Improvements:

  • Added global key information display
  • Added filtering and search capabilities for data sources and mirror tasks
  • Added beginner's guide with visual demonstrations
  • Added product workflow demonstration videos

Mirror Engine & Management Service Optimizations:

  • Fixed a state storage error that affected checkpoint restart functionality for some data sources
  • Optimized logging: reduced non-critical logs and improved log readability
  • Free trial bug fixes: Fixed issues where some new users couldn't activate $300 credit coupons and billing problems

Connector Updates:

  • MySQL: Fixed checkpoint storage anomalies that caused unnecessary warning logs
  • Sybase:
    • Fixed transaction log format that didn't support data rollback in row-level lock mode
    • Fixed parsing errors for some NULL fields
    • Fixed checkpoint progression issues in large transactions and frequent dense transaction scenarios
    • Fixed parsing failures caused by abnormal log storage structure after multiple table schema changes
    • Optimized transaction log parsing process: changed from mixed reading/parsing of all logs to prioritized reading of transaction start, commit, and rollback events before parsing transaction details, improving overall performance by approximately 100%
  • ClickHouse:
    • Modified behavior when fast write mode is enabled: for data consistency, data deletion no longer uses TTL and delete_time combination for data cleanup, now only records is_delete field and batch deletes is_delete=1 data after table optimization
    • When fast write mode is enabled, automatically creates a tablename_view view that automatically adds FINAL keyword and queries only is_delete=0 data for user convenience

We're continuously working to improve ChPulse and add new features. For upcoming features, please check our Roadmap.
