- stored_patterns - stored_patterns
- body_mining - body_mining
pattern_versioninteger nullable
Stored pattern version used. Null for body mining.
pattern_coverage_pctnumber double nullable
Percentage of all matching rows with a nonempty pattern at the selected version. Null for body mining.
represented_countinteger nullable
Exact rows represented by the returned stored-pattern groups. Null for body mining.
remainder_countinteger nullable
Matching rows outside returned groups, including other versions, unstamped rows and the long tail. Null for body mining.
scanned_countinteger required
Rows scanned: the sample size for body mining, or the full matching count for stored-pattern aggregation.
total_countinteger required
Total log rows matching the filters in the window, before sampling. Use with scanned_count to scale per-pattern counts when sampled is true.
sampledboolean required
True when the window held more rows than the sample cap, so patterns were mined from a deterministic, evenly-distributed sample rather than every matching row.
sample_coverage_pctnumber double required
Share of the window's log rows that were eligible for sampling (0–100). Below 100, the scan was bounded to evenly-spaced time slices across the window to keep the query within its execution budget; rows outside the slices could not appear in the sample.
