Source

InfluxDB: What are the series cardinality limitations?

InfluxDB is sensitive to high-cardinality data. High cardinality increases RAM usage and can trigger out-of-memory errors, making it unsuitable for some workloads with many unique tag combinations.

Source

Vector: Can I use Vector for commercial purposes without paying?

Vector appears to have no built-in paid tier distinction and is offered as unified open-source software. However, commercial support options or enterprise services may exist beyond the open-source distribution.

Source
