I released an open source library for telemetry encoding and compression on IPFS.
It transforms an arbitrary array of json values into a columnar representation, compresses the columns, and stores the result on IPFS.
For telemetry data the compression can be very good, much better than just using gzip compression on the json array. Since there seem to be several people using IPFS for storing sensor data or other time series data, I thought this might be useful.
Here is a blog post describing how it works in detail.
