InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
For opcodes you can also use a third option: you use a single struct for all opcodes, and size it to support a fixed number of arguments. Most opcodes probably won't need more than 4-5 arguments. If those argument values are small enough (e.g. u16), you don't need that much space. You can find an example of this here, with the Instruction type only taking up 12 bytes.
