Despite from the version number and unusually long release cycle, this is a complete re-write. This means it's not a drop-in replacement of previous versions, and it may surprise you in certain cases. However, it's highly recommended to start integrating the new JDBC driver and Java client, not only for more features but also better performance - please refer to #768 for details.

  • KNOWN ISSUES

    • new driver com.clickhouse.jdbc.ClickHouseDriver does not work with version before 20.7
    • java.io.IOException: HTTP/1.1 header parser received no bytes when using JDK 11+ and http_connection_provider is set to HTTP_CLIENT
    • RESOURCE_EXHAUSTED: Compressed gRPC message exceeds maximum size when use gRPC - please increase max_inbound_message_size
    • select 1 format JSON works in http but not grpc, because grpc client is not aware of response format
    • gRPC is "slow" by default because it uses gzip instead of lz4 - see ClickHouse/ClickHouse#28671
    • many connection properties are gone - please use custom_http_params and maybe custom_http_headers instead
    • NPE when query null Date/DateTime - see #797 (will be fixed in 0.3.2-patch1)

  • NEW FEATURES

    • Java client and JDBC driver are now in different modules
    • Replaced data format from TabSeparated to RowBinary
    • Support both HTTP and gRPC - Native/TCP will be available in next release
    • Support more data types including Bool, Date32, Geo types, and mixed use of nested types(e.g. array of tuples)
    • Enhanced pipeline for better performance and less memory footprints - still plenty of room to improve according to ranking here
    • More JDBC APIs(especially those related to metadata) are implemented
    • Better date time and time zone support

  • BUG FIXES

    • stale connection validation to mitigate failed to respond issue
    • parsing NaN and Inf/-Inf
