So why would anyone want to put alot of data into a browser? Well, for a lot of the same reasons that edge computing and distributed computing have become so popular.

You get the data a lot closer to the user and you don’t have to pay for the compute ;) 

… this sounds great but as I found out during this conversation it's not as easy as it might seem! 

There are a lot of trade-offs that need to be evaluated when moving data and analytics to the client.

 

Nick Rabinowitz  Senior Staff Software Engineer at Foursquare has a ton of experience with this so he volunteered his time to help us understand more about it.

If you are not familiar with the Arrow data format it might be worth checking out

 

Apache Arrow defines a language-independent columnar memory format for flat and hierarchical data, organized for efficient analytic operations on modern hardware like CPUs and GPUs. The Arrow memory format also supports zero-copy reads for lightning-fast data access without serialization overhead
