Bumps com.clickhouse:clickhouse-jdbc from 0.6.5 to 0.7.0.

Release notes

Sourced from com.clickhouse:clickhouse-jdbc's releases.

Release v0.7.0

Deprecations

  • Following deprecated components are removed:
    • clickhouse-cli-client
    • clickhouse-grpc-client

Important Changes

  • [client-v2] New transport layer implementation is used by default. It is still possible to switch back using old implementation by setting com.clickhouse.client.api.Client.Builder#useNewImplementation to false. (ClickHouse/clickhouse-java#1847)

New Features

  • [client-v2] Now there is an easy way to set custom HTTP headers globally for client and per operation. See com.clickhouse.client.api.Client.Builder.httpHeader(java.lang.String, java.lang.String) for details. (ClickHouse/clickhouse-java#1782)
  • [client-v2] Now there is a way to set any server settings globally for client and per operation. See com.clickhouse.client.api.Client.Builder.serverSetting(java.lang.String, java.lang.String) for details. (ClickHouse/clickhouse-java#1782)
  • [client-v2] Added support for writing AggregateFunction values (bitmap serialization). !! Reading is not supported but will be added in the next release. (ClickHouse/clickhouse-java#1814)
  • [r2dbc] Defer connection creation. This allows pool to create a new instance on every subscription, instead of always returning the same one. (ClickHouse/clickhouse-java#1810)

Performance Improvements

  • [client-v2] Improved reading fixed length data like numbers. It is possible to configure readers to use pre-allocated buffers to avoid memory allocation for each data row/block. Significantly reduces GC pressure. See com.clickhouse.client.api.Client.Builder.allowBinaryReaderToReuseBuffers for details. (ClickHouse/clickhouse-java#1816)
  • [client-v2] New API method introduced to read data directly to a POJO. Deserializers for POJO classes are compiled into bytecode (with help of https://asm.ow2.io/ library) and optimized for each schema. It is great performance boost because data is read without copying it into temporary structures. Code can be optimized by JVM while runtime as SerDe code is implemented without reflection using JVM bytecode. Using bytecode makes handling primitive types without values boxing. (ClickHouse/clickhouse-java#1794, ClickHouse/clickhouse-java#1826)
  • [client-v2] Optimized reading columns - internally data is read into map of column-values. It is done to allow reading same column more than once. Previously map was cleared each row what caused a lot internal objects creation. Now values are overridden because schema doesn't change between rows. (ClickHouse/clickhouse-java#1795)
