Koalas: Add index_col for spark IO reads.

Created on 9 Sep 2019  路  3Comments  路  Source: databricks/koalas

We should provide index_col argument for spark IO reads to avoid creating default indexes in the case index columns are known.

  • read_csv
  • read_delta
  • read_table
  • read_spark_io
  • read_parquet
enhancement good first issue
