Hey there, just wondering what novel solutions this brings to the table? Interested to hear what this solves better than other options.

Interestingly, someone posted this here. I am the contributor of this repo. This repo generally introduces LSM-tree into PostgreSQL via foreign data wrapper approach. Your question may turn into "what's the pro of LSM-tree over B+tree(PostgreSQL)". One sentence for this, fatser data ingestion. You can check my talk in PGCON2020 few days ago. I think it will upload in Youtube.

BTW, we have designed a new super cool data structure, where we we wrap it into a database engine, then put it back to PostgreSQL, even okay for MYSQL (actually easier). The repo is a byproduct for us.
