processes event messages
You must include `bootstrap.servers` in consumer properties with a list of
Kafka brokers in the format `<BROKER_1>:<PORT_1>,<BROKER_2>:<PORT_2>,...`.
In some cases, you may need to retrieve consumer properties at runtime. For
example, when `bootstrap.servers` is unknown or not static.
-The `isolation.level` property in `consumerProperties` determines how Druid
reads messages written transactionally.
-With `read_committed`, which is the default in Druid, only committed
transactions are read.
-If you use older versions of Kafka without transaction support, or you want to
read even aborted transactions, set `isolation.level` to `read_uncommitted`.
+The `isolation.level` property determines how Druid handles transactional
Kafka messages. Although standard Kafka consumers default to
`read_uncommitted`, Druid's ingestion engine defaults to `read_committed`. This
ensures that only finalized data is indexed and aborted transactions are
ignored. If you need to use legacy Kafka brokers or don’t want Druid to consume
only committed transactions, explicitly set `isolation.level` to
`read_uncommitted`. Note that using `read_uncommitted` remo [...]
If your Kafka cluster enables consumer group ACLs, you can set `group.id` in
`consumerProperties` to override the default auto generated group ID.
