Time-series design: series identity and cardinality trade-offs
The news at the time
The article author proposes storing repeated series dimensions in a separate metadata table and referencing them with a compact identifier. This describes a design proposal rather than a guaranteed storage saving.
The author cautions against using high-cardinality fields such as request IDs and session tokens as series identity, because the benefit depends on repeated samples sharing an identity.
Follow-up checked during renewal
No additional follow-up fact was established in this renewal. This does not establish that nothing changed.
What to review before applying this
Compare ingestion rate, dimension cardinality, retention and query patterns on representative data. The reported numerical savings are not reproduced in this brief, and the author’s proposal should not be generalized to every time-series engine.
