This blog series will examine the tools, techniques, and strategies we have utilized to achieve this goal. In this testing strategy, we execute a copy (replay) of production traffic against a system’s existing and new versions to perform relevant validations. This approach has a handful of benefits.

Over the course of this post, we will talk about our approach to this migration, the strategies that we employed, and the tools we built to support this. This allows the app to query a list of “paths” in each HTTP request, and get specially formatted JSON (jsonGraph) that we use to cache the data and hydrate the UI.

Global caches like the InnoDB buffer pool and MyISAM key cache and session-level caches like the sort buffer, join buffer, random read buffer, etc. Global memory caches are static in size as they are defined solely by the configuration of the database itself. Do these queries use more caches?

With all of this in mind, I thought improving the speed of my own version of a slow site would be a fun exercise. In that spirit, what we’re looking at in this article is focused more on the incremental wins and less on providing an exhaustive list or checklist of performance strategies. Compressing, minifying and caching assets.

In this study, the diagnosis and resolution of an outage in a global Internet service, Etsy.com, was explored in an effort to uncover which cognitive strategies (specifically, heuristics) are used by engineers as they work to bring the service back to a stable state.

Bitmap Index Scan The planner chooses this index scan method when the query asks for a large enough amount of data that can leverage the benefits of the bulk read, like the sequential scan, but not that large that actually requires processing ALL the table. Next is the table definition.

Sharing is caring caching. Therefore friend groups all end up accessing similar content, a fact that can be exploited in the backend to improve cache utilisation. Our solver employs a local search algorithm using the “best single move” strategy. Backend processing latency stays fairly constant during this operation.
