TLDR; MySQL did great, generally beating the (perhaps outdated) Neo4j numbers in the posts. I spun up MySQL 8 on my laptop, with a 3G innodb_buffer_pool_size and all else default. No fine-tuning. This research report titled Global Open-Source Database Software Market 2020 by Company, Regions, Type and Application, Forecast to 2025 released by MarketQuest.biz scrutinizes market size, market share, status, trends, competitive scenario, and potential growth opportunities with forecast till 2025. MySQL Transaction : A transaction is a logical unit of work that contains one or more SQL statements.

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.

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.

Provide the JDBC driver jar-file to the command line tool or Neo4j-ETL application. Because Neo4j doesn't have a schema defining properties, there is no such thing as a null value for a property on a node -- the property either exists on the node, or doesn't. Now, all that stuff is fine and dandy, but rows in Postgres don't just exist all on their lonesome; they belong to a table. Neo4j requires every mutating operation on the graph to be run in a transaction, which is great, because it keeps your data safe.
