Calling Delta Merge in DS after every commit

Hi Folks,

I am using an Delta extraction logic in DS to extract large table from ECC (50 Million rows) to the HANA database. The commits in DS job have been configured fopr every 10,000 records. Three questions

1) Should I disable the delta merge in HANA database for this target table prior to the initial load of table. Once the initial load is complete, manually perform the delta merge in HANA is the right approach or

2) Should I be calling manually performing Delta merge in DS job to make sure the table is merged after every commit? If yes how do I call the Delta merge command in DS jobs and how can I do it per commit?

3) Can I invoke Delta merge in DS as part of Delta extraction logic after the initial load is completed in DS?

Any advise will definately be appreciated.

Thanks,
