I think Dean De Leo's work in this space is good. It's certainly the right place to start. This work is on using packed memory arrays (pma) but is focused on in-memory versions of pma. I can recommend these two papers: Teseo: https://dl.acm.org/doi/abs/10.14778/3447689.3447708, and Packed Memory Arrays Rewired: https://ieeexplore.ieee.org/abstract/document/8731468. In Kuzu, I/we will be implementing a pma version of our disk-based CSR-baed join indices, which we also use to store relationship properties, so stay tuned for that!
Thanks for the pointers, I'll look into them. I read your blog post series yesterday and found it very well written and interesting. Gonna read the CIDR paper, too. Fyi, I'm the author of https://github.com/s1ck/graph where we use a read-only CSR and my day job is https://github.com/neo4j/graph-data-science which is built on top of a read-only, compressed CSR. Maybe we can have a chat at some point :)
