2.15 String Column Encoding Reference

2.15.1 Variable-length Encoding

2.15.2 Dictionary Encoding

2.15.3 Column Limits

HeatWave supports two string column encoding types:

• Section 2.15.1, “Variable-length Encoding”

• Section 2.15.2, “Dictionary Encoding”

String column encoding is automatically applied when tables are loaded into HeatWave. Variable-length encoding is the default.

To use dictionary encoding, you must define the encoding type explicitly for individual string columns. See Section 2.8.1, “Encoding String Columns”.
