Documentation indicates that mostly relational database are supported. Is it possible to have a graph dB as a backend? Has anyone done this in the past?

I suggest you test it. download the war files, navigate to WEB-INF -\> classes and then flowable properties. you can see these options:

```
spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.url=jdbc:h2:~/flowable-db/db;AUTO_SERVER=TRUE;AUTO_SERVER_PORT=9091;DB_CLOSE_DELAY=-1

#spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#spring.datasource.url=jdbc:mysql://127.0.0.1:3306/flowable?characterEncoding=UTF-8

#spring.datasource.driver-class-name=org.postgresql.Driver
#spring.datasource.url=jdbc:postgresql://localhost:5432/flowablemodeler

#spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
#spring.datasource.url=jdbc:sqlserver://localhost:1433;databaseName=flowablemodeler

#spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
#spring.datasource.url=jdbc:oracle:thin:@localhost:1521:FLOWABLEMODELER

#spring.datasource.driver-class-name=com.ibm.db2.jcc.DB2Driver
#spring.datasource.url=jdbc:db2://localhost:50000/flowablemodeler

```

I don’t see grahDB but it doens’t hurt to try since i don’t see any reason for it not work. change your options, load up a tomCat server and test it out.

Yes there has been investigation in the past.

See this [forum post](https://forum.flowable.org/t/any-support-for-alternative-persistence-such-as-graphdb/246).

With version 6 the data persistence for Flowable is fully pluggable allowing for alternative implementations such as recent CroachroachDB (see this [blog post](https://blog.flowable.org/2019/07/11/getting-started-with-flowable-and-cockroachdb/)) implementation in 6.4.2 and experiments with MongoDB (see this [blog post](https://blog.flowable.org/2018/08/13/running-flowable-on-mongodb/)).

And there is this [branch](https://github.com/jbarrez/activiti-neo4j) of work done by Joram Barrez using Neo4j.

No, unless the graphDB understands jdbc, it won’t work. The default implementation assumes a relation database and sql.
