At the expense of having to create more complicated queries for analysis and visualisation, the optimisations save at least 103.97 MB or 1-137.99/241.96 = 43% in uncompressed storage space per month. In practice, the storage requirements are lower than those mentioned in the aforementioned theoretical calculations. Over 8 months, I collected a database of 1.04GB of metrics. Using ZSTD with the default level 3, the database can be compressed to just 12.77% of this.
