Building a Columnar, In-Memory Store for Modern Hardware
Besides working on the new experimentation platform in Careem, over the past few weekends I’ve been toying with building a high-performance columnar, in-memory store in Go. Most importantly, I wondered if it is possible to build a nice API while having data laid out in a very cache-friendly way and support indexing. In addition, most of columnar data stores are designed primarily for OLAP and there’s not too many OLTP or HTAP stores built in a columnar fashion so can we build something for OLTP?...
