We just finished up the Open Source Data Stack conference, which is all about this topic. Feel free to check out the reply.

Specifically, open source approaches to the modern data stack where the trend is picking the right tools for the job that revolve around the warehouse central data store.

The pieces discussed were around getting data in (Snowplow events, Meltano ELT), transforming it (dbt), reporting (Superset), getting it back into tools (Grouparoo Reverse ETL), and orchestrating things (Dagster).

It’s crazy how much has changed in the data space in the past few years. You can basically set up a ‘modern data stack’ by swiping a credit card and buying fivetran (EL), snowflake (warehouse), DBT (transform), and hightouch (reverse-etl) for extremely cheap and without the need of an engineer. Just need to know SQL.

I think more companies are going adopt this modern data stack earlier in their data maturity lifecycle.

I have opinions on this. Looots of opinions... Too many, in fact:
