Video of a conference talk about how Jellyfish implemented Citus and Postgres, presented at Citus Con: An Event for Postgres 2023. Jellyfish is a multi-tenant SaaS application based on PostgreSQL. Implementing Citus to distribute PostgreSQL necessitated leaving behind the managed database world of RDS and instead self-hosting PostgreSQL on their own machines. In this talk, Jellyfish shares their journey scaling out PostgreSQL with the open source Citus database extension, so others can learn from the Jellyfish team’s successes and their missteps.
Matt Klein is a Principal engineer on the platform team. Having joined Jellyfish as a founding engineer 5 years ago, pre-series A, Matt has been a software engineer for almost (gulp) 30 years. Matt has worked at early stage startups since 2008 and has worked with PostgreSQL since 2010: application and administration.
Delaney Mackenzie leads a software team at Jellyfish focused on DAGs and data quality. Prior to Jellyfish, he worked on the technical team at a boutique consulting company in Boston, and prior to that he spent almost 5 years at Quantopian (a democratized quant trading startup). While at Quantopian, Delaney worked in many roles, including backend engineer on their event driven backtest system, building out a new educational business line, and running user data science under the auspices of user growth. Delaney has a degree in computer science from Princeton and spent a while doing computational genetics research before joining the startup world.
