Apart from the properties mentioned in the preceding table, we can also configure and
tune the JVM by defining the configurations such as type of GC, GC Logs, Max and Min
memory, and so on in
<$NEO4J_HOME>/conf/neo4j-wrapper.conf
.
To summarize, Neo4j HA architecture meets the enterprise needs in a true sense where it
provides the highest degree of fault tolerance, can operate even with a single machine, and
can expose various configurations, which help in tuning our database to produce maxim-
um throughput.
