Summary

Ports ClickHouse/clickhouse-docs#6483 (upstream HyperDX OTel schema sync) into the Mintlify snippets.

Changes

  • Updated 5 ClickStack OTel metrics schema snippets under snippets/clickstack/:
    • _schema_otel_metrics_exponential_histogram.mdx
    • _schema_otel_metrics_gauge.mdx
    • _schema_otel_metrics_histogram.mdx
    • _schema_otel_metrics_sum.mdx
    • _schema_otel_metrics_summary.mdx
  • Schema deltas mirrored from upstream:
    • MetricName: LowCardinality(String)String
    • StartTimeUnix / TimeUnix / Exemplars.TimeUnix: DateTimeDateTime64(9), DeltaDelta(8)
    • Added INDEX idx_time_minmax TimeUnix TYPE minmax GRANULARITY 1
    • ORDER BY changed to (ServiceName, MetricName, toStartOfHour(TimeUnix), cityHash64(Attributes), TimeUnix)
  • Preserved the MDX {/* ... */} comment marker (converted from the Docusaurus <!-- ... --> form).

Context

Automated upstream sync from hyperdxio/hyperdx docker/otel-collector/schema/seed. i18n translation copies under snippets/<lang>/clickstack/ were not touched, per migration rules.

Notes / ambiguity

  • Only English snippets were updated. The translated copies under snippets/ar|es|fr|ja|ko|pt-BR|ru|zh/clickstack/ still contain the older schemas and will drift until the translation pipeline reruns.
  • Validation (mint validate) OOM'd in the sandbox; changes are byte-for-byte identical to the merged upstream snippets (aside from the comment syntax), so no MDX-level risk is expected.
