That is kind of the point of this repo. If your API implementation is too expensive for lambda move the same container to run on EKS/ECS fargate or ec2. The opposite holds as well - if you can save money by moving it from fargate to lambda then you can use the same container.

Ion has a binary format but is not specifically about real-time streaming. It is a JSON replacement.

Ion originated 10+ years ago from the Amazon catalog team - the team that kept data about the hundreds of millions of items available on Amazon. Nearly every team in the company called the catalog to get information about items all the time - scanning the entire catalog, parts of the catalog, millions of individual item lookups every second, etc.

They did the math and some very large percentage of network traffic in Amazon Retails data centers was catalog data. If that data, currently in XML or JSON format, was sent in a more compact format it would save some ridiculous millions of dollars every year. So Ion was born and eventually open sourced.

I have my Calibre library store to Dropbox. Remarkable integrates with Dropbox so my library is always in sync!

Works pretty well.

I finally got into emacs using the prelude distribution - https://github.com/bbatsov/prelude

It has sane defaults and contextual tips that help when you're getting started (and can turn off later).

The intent of the stored schema isn't really for self-description. A typical use case for Avro is data storage over long periods of time. It is expected that the schema will evolve at some point during this time. Therefore you still need to specify a target schema to read the data into which is allowed to be different than the stored schema. Avro then maps the stored data into the target schema by using the stored schema. Most avro libraries expect you to get the target schema from a separate source before reading data.

Ion has functions to turn Ion into JSON which will, of course, lose information. Annotations are dropped, decimals turn into a JSON number type which may lose precision, etc.
