如何简化数据工作流程并推动业务成功？

Time series is a critical part of Observability at Pinterest, powering 60,000 alerts and 5,000 dashboards. A time series is an identifier with values where the values are associated with a timestamp. Given the widespread use and critical nature of time series, it’s important to give engineers the ability to adequately express what operations to perform on the time series in a readable, understandable, and efficient manner. In this post, we will cover the background of time series at Pinterest, the goals of designing an expressive time series language, and some examples of how we are using this language today.

A month ago I landed a pull request to Winch, Wasmtime's baseline (non-optimizing) compiler, to add support for a number of WebAssembly instructions. Shopify is working on Winch to make Wasm compilation faster. I learned a number of important parts of the codebase and how to test the changes I made which I'll outline below.

Adding support for a WebAssembly instruction means that when Winch encounters a given instruction, it emits zero or more native machine code instructions to perform the operation while ensuring the WebAssembly stack is in the correct state and that CPU registers are appropriately allocated or freed.

Although the pattern is very striking, it’s constructed of only two shapes: nested circles and squiggly lines.
