Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.

Utilize explicit partitioning to enable these capabilities:

Explicit partitioning allows your application to perform a rolling upgrade.
Because partition assignments remain stable, the upgrade does not move load to other receivers.
Each receiver can use the fromTimestamp replay parameter to replay events for its assigned partitions without affecting events sent to other receivers.

The Keep Alive event is sent every 15 seconds when no other event is sent.
