The segment of the table's partitions to scan in this request. For partitioned paths in Hive-style of the form key=val, crawlers automatically populate the column name.In this case, because the GitHub data is stored in directories of the form 2017/01/01, the crawlers use default names like partition_0, partition_1, and so on.You can easily change these names on the AWS Glue console: Navigate to the table, choose Edit schema, and rename partition_0 to … to In your ETL scripts, you can then filter on the partition columns.
