PragmaTwice opened a new pull request, #1871:
URL: https://github.com/apache/kvrocks/pull/1871

   In this PR, CBOR is used as a storage format alternative (written to/read 
from hard drive) for the JSON data type (RedisJSON).
   
   [CBOR](https://cbor.io/) (RFC 8949) is a binary data format compatible to 
the JSON data model, hence it has more efficient encoding/decoding performance 
and more compact data size.
   
   From my observation and simple benchmark, using CBOR instead of JSON as a 
storage format and (JSON document testing datasets from 
RedisJSON](https://github.com/RedisJSON/RedisJSON/tree/master/tests/benchmarks/datasets),
 kvrocks speed up its performance of `JSON.GET` and `JSON.SET` by ~5%, and its 
storage usage reduced by more than 10%.
   
   NOTE: The default storage format of JSON data type is still JSON.
