SnapshotEvaluator.spikes loaded RuleContext.window("query_snapshot", 7)
as QRecords on every snapshot evaluation (every collection interval on
the worker). kof22 writes ~33,000 query snapshots a day, so by day 7 that
is ~230,000 records per evaluation.
history() now reads the window in BATCH_SIZE keyset pages (only OK and
PARTIAL snapshots, as before) and keeps per statement only the current
interval time, the latest capture time and earlier interval times in a
primitive double array. Median, twelve-sample baseline and the one-hour
absence rule are unchanged (SnapshotEvaluatorTest still passes).
SpikeHistoryBoundedTest counts every query snapshot QQQ materializes:
2,500 samples never exceed one 1,000-row page, failed snapshots and
samples outside the window are excluded, the current interval is found.
