Why the models rank ClickHouse — on best time-series databases for high-cardinality observability data
“Its columnar storage engine stores high-cardinality labels as standard attributes rather than creating an inverted index for every unique label combination, allowing petabyte-scale ad-hoc analysis of logs, traces, and metrics without memory-bloat or indexing overhead.”
Why the models rank VictoriaMetrics — on best time-series databases for high-cardinality observability data
“Excellent ingestion efficiency, compression, MetricsQL/PromQL compatibility, simple single-node operation, and independently scalable cluster components make it the best default for high-cardinality metrics; near-tied with ClickHouse, assuming conventional observability metrics rather than arbitrary wide events”
