Users who need to disable the event consumption optimization (e.g. to avoid memory pressure during replay or migration) previously had to either set a JVM system property or override the entire EmbeddedEventStore bean in their autoconfiguration. The new EmbeddedEventStoreProperties class exposes the most relevant tuning parameters via application.properties: axon.eventstore.optimize-event-consumption=false axon.eventstore.cached-events=5000 axon.eventstore.fetch-delay=500ms axon.eventstore.cleanup-delay=5s The JVM system property optimize-event-consumption continues to work unchanged. The default for all settings remains the same as before. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Users who need to disable the event consumption optimization (e.g. to
avoid memory pressure during replay or migration) previously had to
either pass a JVM system property or override the auto-configured
EmbeddedEventStore bean entirely.
A new EmbeddedEventStoreProperties class exposes the most relevant
EmbeddedEventStore builder parameters under the axon.eventstore prefix:
axon.eventstore.optimize-event-consumption (default: true)
axon.eventstore.cached-events (default: 10000)
axon.eventstore.fetch-delay (default: 1000ms)
axon.eventstore.cleanup-delay (default: 10000ms)
The JVM system property optimize-event-consumption continues to work
unchanged. All defaults are identical to the previous behaviour.
Reference guide updated with a description of each property and a note
on the memory implications of the count-based cache limit.
