✨ What's the context?
Context is described in public PRD: https://docs.google.com/document/d/1LcUkGfWL4aKFys0MRSNjKgo8NML2gS3VUtf1GQFKF_4/edit?tab=t.0
This is the first phase of the module, which includes all schema and result functions from prd, seat-non-bids, and analytics tags. For now, only account configuration is supported.
The implementation supports rule caching to reduce heavy-weight parsing. The following properties are available for cache configuration:
hooks.pb-rule-engine.rule-cache.expire-after-minutes- TTL for ruleshooks.pb-rule-engine.rule-cache.max-size- cache sizeSince broken configs are not cached and must be parsed on each request, a single broken config can significantly degrade PBS performance. To mitigate this, exponential backoff has been implemented for parsing. The following properties are available for backoff configuration:
hooks.pb-rule-engine.rule-parsing.retry-initial-delay-millis- initial delay in millisecondshooks.pb-rule-engine.rule-parsing.retry-max-delay-millis- maximum delay in millisecondshooks.pb-rule-engine.rule-parsing.retry-exponential-factor- backoff factorhooks.pb-rule-engine.rule-parsing.retry-exponential-jitter- jitter🧪 Test plan
