Shared Indexes and Joins in Streaming Databases

This article is an English version of my previous post, which was originally published in May 2022. It also summarizes my undergraduate thesis on streaming indexes and streaming joins. Half a year has passed since then, and the implementation in RisingWave has changed significantly. But the basic idea remains the same: push data to the remote node instead of pulling it.
