Hi David,
Thank you for your reply! But I still have questions.
I want to know more information about the sequence about load data query.
For example, as the normal process, a RDF file named rdf.nt load into Rya,
first, A.class get the data, B.class handle the data as the predefined index
structure, and C.class load data into Accumulo.
For a query, 1.class get the query instance, 2.class parse statement, 3.class
connect to Accumulo and obtain the data.
There are so many similar files and classes in Rya-project, so I will be
confused, I don't know which one is core and effective. I can't know in real
time which class to call when performing an operation.
My question looks stupid, so please forgive me.
Best,
Weiqi
