How to dynamically add custom Steps at runtime?
I am maintaining a graph engine service that provides different products. I have found that some complex scenarios cannot get query results through native Steps. Special business logic operations are required to implement custom special syntax through business code. The current custom syntax is done through @GremlinDsl, which is generated at compile time and the code is written in my own service. I hope that this special syntax can be defined by the product itself and pushed to the specified directory and loaded at service runtime. Can the TinkerPop framework do this? How can it be done? What is the specific implementation method?
Solution
You can use Groovy for all manner of trickery (AST manipulation, basic metaprogramming APIs, etc), but I'd take care with depending on it given the security risks associated with it. TinkerPop has been slowly moving away from it, first with bytecode based requests and more currently with the Gremlin ANTLR grammar. There is a general consensus that the latter will ultimately replace groovy/bytecode going forward into the future. I'm not sure if any of that impacts your decisions on how to maintain your service using 3.5.x but I thought it was important to share.
Apache TinkerPop is an open source graph computing framework and the home of the Gremlin graph query language.
