msglc

msglc is a Python library that provides a way to serialize and deserialize json objects with lazy/partial loading containers using msgpack as the serialization format.

It can be used in environments that use msgpack to store/exchange data that is larger than a few MBs if any of the followings hold.

1. After cold storage, each retrieval only accesses part of the stored data.
2. Cannot afford to decode the whole file due to memory limitation, performance consideration, etc.
3. Want to combine encoded data into a single blob without decoding and re-encoding the same piece of data.

Installation

msglc is a pure Python library and can be installed using pip.

pip install msglc

The only dependencies are msgpack and bitarray.

msgspec

msgspec is an alternative library that provides better decoding performance compared to msgpack. It is recommended to use msgspec.

pip install msgspec[msgspec]

numpy

numpy arrays can be serialized and deserialized, to use this feature, install numpy.

pip install msglc[numpy]
