I have a question related to configuring the encoder. I couldn't locate in the specifications how to configure this part, so decided to ask here.

During compression, is there an encoder config/parameter that ensures:

A single literal stream LSTREAM1 is used in the zstd compressed blocks
consequently, the jump table is skipped

Thank you :)

There is no such parameter (at least not yet).
Currently, the encoder selects automatically which one (1-stream, 4-streams) to employ,
mostly based on the size of literals buffers.
The single literal stream is limited to 1 KB max. This is a hard format limitation.
As a consequence, single stream cannot be unconditionally selected.
