What are the known limitations of the AWS Glue connector?​

Atlan currently does not support the following:

  • Parsing MAP type objects for columns and nested columns.

What does the sizeBytes property mean in AWS Glue crawls?​

In Atlan, the sizeBytes property is derived from the SizeKey parameter returned by AWS Glue. This value represents the total size of all files associated with a table, in bytes. For example, if a Glue table points to an S3 location with three files, each 1 MB in size, sizeBytes shows 3,145,728 bytes (3 × 1,048,576). For more information, see Parameters set on Data Catalog tables by crawler - AWS Glue.
