Zstd compressionLevel #145

Closed auko-lq closed 1 year ago

auko-lq commented 2 years ago

Currently the Zstd compressionLevel is hard-coded, Can you add a method to modify compressionLevel? Thx.

Hi, looking at the code (CompressionParameters), only DFAST Strategy is supported. But depending on complexity there are a lot of other strategies to choose, which are not implemented.

So I believe that a good amount of work needs to be done to implement other strategies in order to support other compression levels.

In addition, the zstd buffsize parameter setting should also be supported.

Only the default level is supported (implemented) right now, so it doesn’t make sense to allow it to be configurable at this time
