Question please?

I need to save a JSON object to a Redis Database.

I am able to save, but I can't decrypt back from Redis.

It seems like I need to add a Stream Identifier to the compressed string to indicate it's a Snappy type.

`
/**
* All streams should start with the "Stream identifier", containing chunk
* type 0xff, a length field of 0x6, and 'sNaPpY' in ASCII.
*/
private static final byte[] STREAM_START = {
(byte) 0xff, 0x06, 0x00, 0x00, 0x73, 0x4e, 0x61, 0x50, 0x70, 0x59
};

`

This is the class the guys in Java are using..
https://programtalk.com/vs/?source=netty/codec/src/main/java/io/netty/handler/codec/compression/SnappyFrameEncoder.java

My question is, how can I generate a stream with those characteristics?

The rest of the payload it's a json object.

I.e.

const jsonObjectBody = '{ "myObjKey": "myObjValue" }';
const jsonObjectBodyStreamWithStreamIdentifier = ?????

Thank you very much!

Update:

The library works fine, very fine. But the Snappy encoding I need to do should return the stream identifier as follows:
"\x82SNAPPY\x00\x00\x00\x00\x01\x00\x00\x00\x01\x00\x00"

instead of:

�\x06\x00\x00sNaPpY\x00�\x03\

I wonder how to achieve the identifier as in the first example?

Update: The encoding in the server side was using Java-only encoding. Not an issue .
