Writes messages to Salesforce, routing each Kafka topic to its own sObject configuration.

Introduced in version 4.85.0.

Consumes batches of messages and writes them to Salesforce. Each message must have a topic field (set by the per-topic processor) and a data field containing the Salesforce record fields. The topic is used to look up the correct topic_mappings entry which defines the sObject, operation, and write mode.

Realtime mode uses the sObject Collections REST API (synchronous, up to 200 records/call). Bulk mode uses the Bulk API 2.0 (asynchronous, polls until complete).
