Hi, we are trying NFS as deep store for pinot in an off cloud setting, wondering if there’s anything we should be careful about? Also, did anybody try MinIO as deepstore for pinot?

We use NFS too, works well so far. The only issue is pushes of large data size can take longer since all payload has to go through controller

got it thanks

Also for NFS, you need to set controller vip configs with a load balancer in front of all the controllers so that request will be distributed to all the pinot controllers. Basically when you upload a segment, you want the segment download url to be

pinot-controller:9000

, not

pinot-controller-2:9000

good point thanks
