R/3 ABAP Data Flow v/s Direct Table read

Hello Experts - In my SAP ECC source table I have around 10 Billion records.... and I need to process these records through Data Service.

Its a Single Table and each record length is quite big.

What is the best method to make the data transfer process faster...

- ABAP Data Flow  ?

- Direct read from a table ?

I have seen couple of post but this is nowhere properly mentioned what to use where ?

I really need a proper and logical explanation which method I should Use here ?

Streaming data from SAP using RFC: Reads data from SAP applications using regular data flows

and supports tables (for small data sets only) and extractors.

ABAP : Reads data from SAP applications using ABAP data flows and supports tables, hierarchies, extractors, and functions with scalar arguments, good for .

Based on the number of records you mentioned, I would say ABAP is your better option. Because for large amounts of data performance is generally better when you extract data  using ABAP data flow.
