   @lwhite1 thank your for advice. But it I try this as workaround for https://github.com/apache/arrow/issues/13760 to save Arrow data Vector in Parquet instead of Arrow file format. But anyway this feature would be useful in future in java based solution for data export like QuestDB database

   Hi @igor-suhorukov, 
   
   Unfortunately, writing to Parquet files is not yet supported in Java. You would have to hand-off the data to CPP and use the CPP Dataset API

   Related PR #14151 but it works only from ArrowReader, not from VectorSchemaRoot
