ODC Appreciation Day : HCC compression


My last minute addition to ODC Appreciation Day – oldie but goodie – Hybrid Columnar Compression. A real game changer when it comes to Data Warehouse systems, allowed us to pack up many times (like > 10x) more data in the same space at the expense of some CPU load. With 4 different levels you can choose how much exactly do you want to trade off the resources. And together with ZFS storage no extra licensing is needed – really best bang for the buck possible.

Looking back I believe it was really the best feature we could have for DWH business…
