Hi @홍원종 Azure SA ,
If you cannot use the AWS data connector, my understanding is that you can use this script to create the table: https://github.com/Azure/Azure-Sentinel/tree/master/DataConnectors/S3-Lambda#edit-the-script
After the script runs, the table will be created but you need to ingest the data into the custom table to be able to query it. The custom table is where it's stored in Log Analytics.
You can check the schema before ingesting, and after it's created you would find the table under "Custom Logs." https://learn.microsoft.com/en-us/azure/sentinel/data-source-schema-reference
Let me know if this addresses your question.
