Hi folks,
My HADOOP team is looking for a way to replicate all ECC data into HADOOP system using HANA as the middle man. I've been doing some research and mostly I'm finding SCN posts on doing the opposite; consuming aggregated or reduced HADOOP data into HANA. To me that's how HADOOP should be leveraged but I'm trying to see what others are doing. My questions;
1) Is anybody doing this (loading all HANA data into HADOOP on daily basis)? Is this really best practice and is there any good documentation on this approach?
2) Does anybody know much about HANA Dynamic Tiering? I was asked to look into this and as far as I can tell it seems to be intended for BW scale out system. Our HANA system that contains SAP replicated data is a single node scale up system so I do not think this can be leveraged.
3) I'm not clear on how delta mechanism would work. Is it possible to somehow use log files in HANA and pull inserts/updates/deletes this way?
Thanks,
-Patrick
