Will Carbonata be integrated with Spark in the future? Can Spark version 3.1.2 be integrated with Carbonata

Yes, the community is considering spark 3.3

Comparing Spark3.1.1 and Spark3.1.2, the parameter list for the writeAndRead method in the DataSource class has increased from 4 to 5. The link between the two versions of code is as follows: https://github.com/apache/spark/blob/v3.1.2/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/DataSource.scala https://github.com/apache/spark/blob/v3.1.1/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/DataSource.scala Due to modifications to the writeAndRead method of the DataSource class in Spark3.1.2, this will result in issues with integrating Carbondata2.3.0 with Spark3.1.2. The reason for the problem is that CarbonReflectionUtils in carbondata2.3.0 references Spark's writeAndRead method. The link for CarbonReflectionUtils is as follows: https://github.com/apache/carbondata/blob/branch-2.3/integration/spark/src/main/scala/org/apache/spark/util/CarbonReflectionUtils.scala Will the future community integrate higher versions of Spark3.1.2 or Spark3.1.x
