First release! 🎉

This version includes custom Clickhouse dialect for Apache Spark 3.5.x, with following enhancements:

  • support for writing Spark's ArrayType to Clickhouse. Currently only few types are supported, like ArrayType(StringType), ArrayType(ByteType), ArrayType(LongType), ArrayType(FloatType). Unfortunately, reading Arrays from Clickhouse to Spark is not fully supported for now.
  • fixed issue when writing Spark's TimestampType lead to creating Clickhouse table with DateTime64(0) instead of DateTime64(6), resulting a precision loss (fractions of seconds were dropped).
  • fixed issue when writing Spark's BooleanType lead to creating Clickhouse table with UInt64 column instead of Bool.
