Error while data decompression

[gowestyang]

My q query can be executed correctly in a q session. But in qPython, sometimes I receive "Error while data decompression", while other times I can query correctly.
What is the meaning of this error?

Hi there, facing the same issue here.
From observation, this seems to be an issue when you max out 2gb, or 2^21 bytes.

I think this is to do with this line of code here:
https://github.com/exxeleron/qPython/blob/master/qpython/qreader.py#L494

I wonder if there is a limit to the IPC throughput, hence the hardcoded limit? Just want to know what's the speed limit here 😄
