如何提高 ADF 中 ACDOCA 表的复制活动性能？

Question

I am copying data from SAP to Azure Synapse dedicated pool. The table name is ACDOCA from SAP side.

When I try to copy data from ACDOCA to Synapse, firstly it took around 8 minutes to first byte and then failed with internal memory error due to large amount of data in this table.

I have tried partition on calendar date for other tables like BKPF (On CPUDT column) and the performance was increased.

But, I am not able to decide which column should I consider for date partition in Copy Activity in ADF. FYI, AEDAT and BLDAT are not able to resolve the performance issue.

Why I am doing this:

I need the latest data of ACDOCA table from SAP to Synapse daily AND I want to implement a incremental load on this table using date column.

Thanks

Answer 1

I would suggest using the Document number as Delta pointer as ACDOCA or ACDOCU table entries doesn't get modified at all, always new document number gets added when there is new posting happens
