This blog post covers the essential command-line tools and workflows for managing and interacting with InfluxDB 3 Core and Enterprise instances. It assumes users are familiar with InfluxDB 3 Core, which is the open-source version of InfluxDB 3 Enterprise. The CLI commands in Core are identical to those in Enterprise, making it an excellent choice as an edge data collector or for learning purposes. The post provides a comprehensive guide on how to start and stop the server, create and write data to databases using authentication tokens, query data efficiently with SQL and InfluxQL, set up performance-boosting features like last value cache and meta-cache, and delete databases and tables when necessary. The blog also covers the naming conventions for buckets, measurements, fields, tags, and provides examples of how to use these commands in practice, including writing data directly or using cURL to interact with the database.
