I have a scenario, I have hundreds of tables in HANA as source with different schemas in each table, while migrating data to azure ADLS using ADF it is converting decimal data type to decimal(38, 18) by default . how can I migrate all the tables dynamically with their original datatypes as source using ADF? can you do a demo on this please?

Thanks, is it supported on all cluster run time versions?

Can you change the datatypes in databricks delta table?

[NepaleseHeaven]

just quick question, delta table is same as a table right? all the table created in databricks called delta table, is that true?
