NebulaDaoBasic‘s Schema support-show metas

[wey-gu]

Hi @amritagg
I'm glad you're interested in these features.

We need to add methods to NebulaDaoBasic that allow developers to quickly access data without having to write ngql
Just like its other interfaces.https://github.com/nebula-contrib/ngbatis/blob/master/src/main/java/org/nebula/contrib/ngbatis/proxy/NebulaDaoBasic.java

The idea is to extract the more commonly used scripts, as the name of the task item means.

For example, show metas, developers can quickly get schema information by calling the interface, tag, edgeType, etc.

I think underneath it's calling

SHOW TAGS
SHOW EDGES

And then to call

SHOW TAG <FOO_TAG>;
SHOW TAG <BAR_TAG>;
SHOW EDGE <A_EDGE_TYPE>;
SHOW EDGE <B_EDGE_TYPE>;

And put schema info into one object?

If that's the case, I implemented similar functions here as a reference:

That sounds useful! I will have a try to achieve the show the meta-structure of the graph
maybe the output of it will be a map structure like
space:test
tag :[tagA,tagB,...]
edge: [ edgeA,edgeB,...]
tagIndex:[tagIndexA,tagIndexB,...]
edgeIndex:[edgeIndexA,edgeIndexB]
...
