create (n) statement not supported

[bluejoe2008]

I want to use okapi to enable insert nodes/edges into graph via using cypher statements like create (n)
however it throws exception on IRBuilder.process() which tell create statement is unknown
can you give me any suggestion?

Thank you very much!

Hello @bluejoe2008 and thanks for reaching out to us.

First, I'd like to clarify the status of this project as currently not being in development. You can read a more comprehensive answer on why in #950.

Second, the updating clauses of Cypher were not in scope for Morpheus even when development was active. This includes the clauses CREATE, MERGE, SET, DELETE, and REMOVE. In order to create graphs, you will have to make use of the Property Graph Data Sources (PGDS), which provide endpoint-specific formats where nodes can be added in various ways. For example, you can create nodes with full Cypher support in a Neo4j database and connect it to Morpheus using a Neo4j PGDS (example). Or, you can use Scala case classes and create nodes (and relationships) in Scala code and create a Morpheus graph directly from these (example).

I hope this is helpful!

Mats
