Choosing a database is hard, however, maintaining it afterward is even harder. In this post, we talk about elements to focus on, tooling, monitoring, and other aspects of keeping the database up and running.

Databases are complex beasts. They have options for various areas like memory usage, backups, write-ahead-logs, monitoring, replication, and many more. Installing a database is just the beginning, we need to configure it accordingly later on to match our needs. In this blog post we cover the most important settings you should use.

Compares Prometheus and InfluxDB, two popular time series databases. It highlights the key differences between the two in terms of data model, query language, scalability, ecosystem, and pricing.

Here's a quick summary:

Data Model: Prometheus offers flexible querying with its multidimensional model, while InfluxDB is better for data retrieval with its tag-based model.

Query Language: Prometheus uses PromQL, InfluxDB uses InfluxQL (similar to SQL).

Scalability: Prometheus scales horizontally, InfluxDB scales vertically.

Ecosystem: Prometheus integrates well with monitoring tools, InfluxDB offers more integrations overall.

Pricing: Prometheus is free, InfluxDB has a free tier and paid tiers with more features.

Ultimately, the choice depends on your needs. Prometheus is ideal for monitoring and alerting with its flexible data model, while InfluxDB excels at handling large datasets.
