Background/Context

This will allow FOLIO's maximum number of tenants in a cluster to not be bound too early by Kafka resources and consequently reduce costs to host a suitable Kafka cluster for a corresponding multi-tenant FOLIO installation.

Assumptions

• Development will need to occur on module touch points with Kafka to express the enhancements described in the RFC

Constraints

• Kafka topic topology where multiple tenants have their dedicated topics will still be available.

Rationale

Detailed in the RFC

Decision

Provide a configuration option for FOLIO modules to produce messages to a tenant collection topic or a single tenant topic in Kafka.

Implications

• Pros & Cons are detailed in the RFC.
