Transaction

All operations are automatically wrapped in transactions. Example of how to rollback a transaction:

Neo4j::Transaction.run do |tx|
   Neo4j::Node.create
   Person.create
   tx.fail
end

API

• Neo4j::Transaction
• Neo4j::Transaction instance

Neo4j::Transaction is implemented in neo4j-core.

Limitations

• The query api (example Neo4j::Session.query or Person.where) can only return properties because limitations in the Neo4j Server Rest API (this works in the embedded db).
• Transactions are thread confined and can be nested as "flat nested transactions"
