Experiencing huge lag (up to 93 minutes, lasting for 3.5 hours) when processing trail files under specific load. This brings us way beyond the SLA of 5 minutes delay. The nature of this data processing pipeline is based on roughly 20 billing cycles per month. These billing cycles triggers a lot of database operations in a few hours. Burst / batch behavior. Once billing occurs on the source database side, changes are pushed to Coherence via HotCache. There are a few event interceptors triggered when caches are updated by HotCache. After some point, HotCache/Coherence is lagging by more than 93 minutes.
