Boto3 AWS Glue Crawler: how to get last run table changes?

Question

In the AWS console, we can see if a crawler run returned with changes in schema for particular tables:

![crawler ui](/media/postImages/original/IMVS_OmxwOTayK7TSm0yA_6g)

If I were to click on where it says "3 table changes", I would see the names of the tables that changed in that run.

Using boto3 or the API, how can I do that?

Using [get_crawler_metrics](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/glue/client/get_crawler_metrics.html) only returns the number of affected tables, not the names of the tables.

EDIT:

After considering the accepted answer, I've solved my problem by recursively calling the GetTables API. Tables have a last updated timestamp. I used that to check which tables have been updated recently. This is enough for me, as I don't care what happened to the tables, just that they changed recently, because I do this check immediately after the crawler finished a run.

Accepted Answer

I'd suggest using the AWS Glue Data Catalog APIs like GetTable or GetTables to programmatically retrieve the metadata of all tables in a database after a crawler run. By comparing the table metadata before and after a run, you can identify which tables were created, updated or deleted. [Get Table](https://docs.aws.amazon.com/glue/latest/webapi/API_GetTable.html)
[Get Tables](https://docs.aws.amazon.com/glue/latest/webapi/API_GetTables.html)

The crawler logs and AWS Glue console are other options but may not be suitable. For ad-hoc exploration, the AWS Glue console provides the most direct way to see the names of tables affected by a specific crawler run. However, through code, the Data Catalog APIs provide a way to programmatically retrieve this information by comparing table metadata.
