Readonly transactions with Neo4j

Are there any benefits of using Spring @Transactional(readOnly = true) with Neo4j/Neo4j Spring Data ? Should I mark readonly transactions as @Transactional(readOnly = true) or not ?

Transactions marked as readonly are routed to the follower / read-replica nodes in Neo4j. This reduces the load on the leader node(s), allowing them to better serve Write queries.

Since SDN 4.2 (4.2.RC1 at the time of writing) you can use read only transactions.

As of SDN 4.2 you can also define read only transactions.

You can start a read only transaction by marking a class or method with @Transactional(readOnly=true).
