3.4.1.5 Storage

Beside of storing the row data as-is (and indexing each value by default), each value term is stored into a Column Store by default. The usage of a Column Store is greatly improving global aggregations and groupings and enables ordering possibility as the data for one column is packed at one place. Using the Column Store limits the values of TEXT columns to a maximal length of 32766 bytes.

Turning off the Column Store in conjunction of turning off indexing will remove the length limitation.

CREATE TABLE t1 (
  id INTEGER,
  url TEXT INDEX OFF STORAGE WITH (columnstore = false)
);
