To enable this feature, set dbms.transaction.timeout to some positive time interval value denoting the default transaction timeout. The idiomatic use of transactions in Neo4j is to use a try-with-resources statement and declare transaction as one of the resources. Then start the transaction and try to perform graph operations. The last operation in the try block should commit or roll back the transaction, depending on the business logic. Neo4j stores data in nodes connected by directed, typed relationships with properties on both, also known as a Property Graph. It is a high performance graph store with all the features expected of a mature and robust database, like a friendly query language and ACID transactions. You could store the live data in Neo4j and then extract the data you need for statistics/reporting and put into MySQL.
