Overview #

Primary key table is the default table type when creating a table. Users can insert, update or delete records in the table.

Primary keys consist of a set of columns that contain unique values for each record. Paimon enforces data ordering by sorting the primary key within each bucket, allowing users to achieve high performance by applying filtering conditions on the primary key. See CREATE TABLE.
