You can use columnar storage by itself, or in a distributed table to combine the benefits of compression and the distributed query engine. You can use columnar storage by itself, or in a distributed table to combine the benefits of compression and the distributed query engine.
When using columnar storage, you should only load data in batch using `COPY` or `INSERT..SELECT` to achieve good compression. Update, delete, indexes, and foreign keys are currently unsupported on columnar tables. However, you can use partitioned tables in which newer partitions use row-based storage, and older partitions are compressed using columnar storage.
