HELP: Description of different pots for the columns in this table TYPE: OBJECT SYNTAX: POT[(NAME='str',CMPLEVEL=COPY/FAST/DYNAMIC/COMPACT/ARITHMETIC,CRYCONF=CLEAR/VEIL/ENC,POTPAR())...]
Describes pot used to compress and encrypt a list of elements with flags, length, data and attributes. Such a element list is called matrix and will be serialized to a FLAM segment. For this serialization you must define how each column will be compressed and/or encrypted. For this you can define several pots with a certain name and for each column you can assign such a pot by the given name.
The port design could significantly improve compression results. Columns with the same type of date should be assigned to the same pot. The goal should be a minimum number of pots, because each pot needs overhead, but sometimes it would be much better to use more than one pot for the columns.
STRING: NAME='str' - Logical name for a row format (table)NUMBER: CMPLEVEL=COPY/FAST/DYNAMIC/COMPACT/ARITHMETIC - Compression level [DYNAMIC]
COPY - Copy data, no compressionFAST - Fast compression (fast, lower compression ratio)DYNAMIC - Dynamic compression (balanced speed and compression ratio)COMPACT - Compact compression (slow, high compression ratio)ARITHMETIC - Compression for arithmetic data (integer values (type, flags, length, ...)NUMBER: CRYCONF=CLEAR/VEIL/ENC - Encryption mode [ENC if key else NONE]
CLEAR - Clear data, no confidentiality protectionVEIL - Confidentiality protection with veilingENC - Confidentiality protection with encryption
