Hi All, We are exploring Pinot. And have few questions, hope this is a right group to put across if not kindly let me know the right group. ( Question ). Can pinot work with deep storage, we are looking for inverted index and columnar which pretty much solved in pinot servers itself. Should we need deep storage? like hdfs? (Answer we find in ) https://docs.pinot.apache.org/release-0.4.0/developers/tutorials/store-data . Yes you need hdfs or s3 to have persistence. (Overall Question is ) : Does it mean one need hdfs or s3 for persistent storage and you can't make pinot server itself as a persistent layer as incase of ALL pinot server shutdown and started, data will be gone?
