If there are multiple controllers, Pinot expects that all of them are configured with the same back-end storage system so that they have a common view of the segments (e.g. NFS). Pinot can use other storage systems such as HDFS or ADLS
I can't find more info about this. Would any mountable NFS work? S3 for example?
m
Yes. NFS would work. So would any deep store
We have implementations for NFS, ADLS, S3 and GCS
k
If you have S3, you don’t need NFS
m
Correct. S3/ADL/GCS as deep-stores can be shared across controllers without any further need of NFS on top of that.
