Using PostgreSQL Arrays The Right Way
At Heap, we lean on PostgreSQL for most of the backend heavy lifting.[1] each event as an hstore blob, and we keep a PostgreSQL array of events done by each user we track, sorted by time. Hstore lets us attach properties to events in a flexible way, and arrays of events give us great performance, especially for funnel queries, in which we compute the drop off between different steps in a conversio

ndarray modules
In the last two posts I introduced ndarrays, and explained the rationale and implementation details of the library. Â In this post I am going to show a few of the libraries that I have written using ndarrays. Â All of this code works in both node.js and within any browser that supports typed arrays. Â You can run the demos directly in node.js or else test them out in a browser using a bundler like br
