- Import jest from @jest/globals in failover-recovery tests that used the global (ReferenceError: jest is not defined) - Drop fake-timer usage that captured the mocked setTimeout and hung - Type logger.warn/debug spy calls to satisfy strict tsc - Export SCHEMA_MANAGER_INDEXES from db.ts and import it in the schema manager test (ReferenceError) - Make the Goldii-locks#186 migration-count assertion robust to future migrations - Accept opts argument in the indexer-runner-historical-sync getEvents mock
…cks#256) Implement dynamic polling frequency intervals in indexer_runner based on ledger processing load: - Add IndexerRunnerThrottleParameters / IndexerRunnerThrottleState with env-configured base/min/max intervals, idle multiplier, idle threshold and load decrease factor. - adjustIndexerRunnerPollInterval(): the polling wait delay backs off (increases) toward the max when the network is idle and is pulled back toward the min when events are processed. - Wire the poll loop (poller.ts) to size its sleep from the indexer_runner throttle instead of the generic db.ts throttle. Add tests asserting polling wait delays increase while the network is idle, including an integration test that drives pollEvents() through repeated idle cycles.

Summary
Implements dynamic polling frequency intervals in
indexer_runnerbased on ledger processing loads.(
INDEXER_RUNNER_POLL_INTERVAL_MS,INDEXER_RUNNER_MIN/MAX_POLL_INTERVAL_MS,INDEXER_RUNNER_IDLE_MULTIPLIER,INDEXER_RUNNER_IDLE_THRESHOLD_CYCLES,INDEXER_RUNNER_LOAD_DECREASE_FACTOR).adjustIndexerRunnerPollInterval()backs the polling wait delay up toward themax interval while the network is idle and pulls it back toward the min when
events are processed.
poller.ts) now sizes its wait from the indexer_runner throttle.Validation
including an integration test that drives
pollEvents()through repeated idlecycles and asserts the delay grows.
tsc --noEmit,npm test(965 tests), andnpm run buildall pass.Also includes small repairs to pre-existing CI failures so this branch is green.
Closes 256
