Browsers will cache tools popular among vocal, leading-edge developers. There's plenty of space for caching most popular frameworks. The best available proxy data also suggests that shared caches would have a minimal positive effect on performance. Browsers now understand the classic shared HTTP cache behaviour as a privacy bug.

In a small system this may be a table in a central relational database, but it’s best setup as a NoSQL data source using something like Amazon DynamoDB or Apache Cassandra, with a caching client library or at large scale a microservice data access layer.

In particular, he talked about the misattribution potential in a complex microservice architecture where often intermediary results are cached. One of the challenges he described was how to efficiently choose a decision point, when the joint optimization search presented a Pareto frontier in the possible solution space.

It connects to PostgreSQL as a predefined user (whose password must be present in the userslist.txt file) and executes the auth-query to find the user’s password and matches it to the provided value. Once the authentication succeeds: PgBouncer checks for a cached connection, with the same username+database combination. And that is it!

Based on these findings, the authors present four guidelines to get the best performance out of this memory today. Optane DIMMs have lower latency and higher bandwidth than storage devices connected over PCIe (including Optane SSDs), and present a memory address-based interface as opposed to a block-based NVMe interface.

Go to step 1 if more chunks present. This way, log event processing can resume event-by-event afterwards, eventually discovering the watermarks, without ever needing to cache log event entries. Once the high watermark event is received, send all remaining result-set entries to the output before processing new log events.
