Note 3 : Referencing a prefix involves building tables, which are dependent on compression parameters.
|
||||
It's a CPU consuming operation, with non-negligible impact on latency.
|
||||
If there is a need to use the same prefix multiple times, consider loadDictionary instead.
|
||||
Note 4 : By default, the prefix is interpreted as raw content (ZSTD_dm_rawContent).
|

Note 4 : By default, the prefix is interpreted as raw content (ZSTD_dct_rawContent).
|
||||
Use experimental ZSTD_CCtx_refPrefix_advanced() to alter dictionary interpretation.

A full dictionary is more costly, as it requires building tables.
