circ.edges.afferent_edges(node_ids[0]) fills my memory

[markovg]

Calls to circ.edges.afferent_edges even for one target neuron is filling my 32GB of ram almost instantly.

Is this expected behaviour? What is the correct way to get synapse properties without filling memory?

I can confirm this unexpected behavior. It's not just eating up memory it is also slow.
Things do work when accessing each edge population separately:

But that is of course just a workaround.

Thanks @MWolfR for the workaround. We'll work with that for now.

The zenodo example includes the offending idiom above on the last line ... to the effect of crashing my reservation due to exceeding memory quota. Might be good to remove it for now (and e.g. replacing with the workaround) to avoid offending unsuspecting users
