This is just an idea of using simdjson in pandas, partially following #58278.
I also explored
pysimdjson, which would be viable and do the exact same thing that this PR does. Although, it only decodes, while creating an extension permits to create an encoder on top of simdjson.From the current PR, compared to ultrajson, it shows no performance increase and memory consumption remained similar, while with pysimdjson seems to increase the memory consumption slightly.
