Redis® is an in-memory database that provides blazingly fast performance. This makes it a compelling alternative to disk-based databases when performance is a concern. Redis returns a big list of database metrics when you run the info command on the Redis shell. This blog post lists the important database metrics to monitor.

Now let’s look at how we designed the tracing infrastructure that powers Edgar. Our distributed tracing infrastructure is grouped into three sections: tracer library instrumentation, stream processing, and storage. A second job taps the data feed from the first job, does tail sampling of data and writes traces to the storage system.

When you do a database restore, you want to have it done as soon as possible. And the database is unusable until the restore is done. Our tests showed physical database restores up to 5x faster than the logical ones. We aim to port it to Azure Blob and FileSystem storage types in subsequent releases.
