ScyllaDB (a next-gen Cassandra clone) is a "wide-column" database, or better called "advanced key/value".
This is very different from columnar/column-oriented databases which are still (usually) relational and just store data by columns instead of by rows for OLAP (large-scale analytics) usage.
- PeterCorless 4y agoCorrect. A wide-column database like ScyllaDB is still a row-based store. Usually described as a "key-key-value" because it has both a partition key for data distribution and a clustering key for sort-ordering within a partition. Not the same-same as a "column-store" like Druid or Clickhouse or Pinot. [Disclosure: I work at ScyllaDB.]
