Neo4j is a graph database management system that offers an ACID-compliant transactional database with native graph storage and processing. Neo4J is like the ‘MySQL’ of graph databases. In Neo4j, It is possible to configure Neo4j to terminate transactions whose execution time has exceeded the configured timeout. 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.

Being a graph database, Neo4j is not serving data in a relational way, nevertheless thanks to this driver it’s possible for projects that are using the classic JDBC connector in the relational paradigm to interact with Neo4j.

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. For searches I'd go with the Neo4j-Lucene integration if that fits your needs.

I'm trying to migrate the database to Neo4j, just for study and learn about graphs. In this case, my queries are about: What was the last transaction of an account? How many transactions an account had in the last month, or year?

Neo4j also comes in handy for financial risk reporting and compliance. NEO4J, the graph database, can be used to provide answers that are very tricky for relational databases, including providing diagrams to show how SQL tables relate to each other, and the shortest chain of relationships between two tables, as David Poole demonstrates 2019-05-23 · Neo4j Streams Producer: a transaction event handler events that sends data to a Kafka topic. Neo4j Streams Consumer: a Neo4j application that ingest data from Kafka topics into Neo4j via templated Cypher Statements. Kafka-Connect Plugin: a plugin for the Confluent Platform that allows to ingest data into Neo4j, from Kafka topics, via Cypher Install Neo4j Python Driver.
