Re: [rdf4j-dev] How is it going

[Heshan Jayasinghe <shanujse@xxxxxxxxx>]

Hi Håvard,

I checked our AST with multiple minCount and multiple Shapes it working fine.I go though research papers and tutorials last days lambda expressions and Iterator little bit new to me.

I go though with plan and some places i couldn't understand properly. Now i am writing iterator implementations to OuterLeftJoin, GroupBy, Count. Can you please tell me what is the validation plan in  ShaclSailConnection and what is the difference between ShaclSailConnection and mincount validation.

I think Groupby section logic (condition) we right in main class and we retrieve that condition  to out GroupBy class. is that correct? 

I will commit my code to Github after implement this OuterLeftJoin,GroupBy,Count classes.

Thank you,

regards,

Heshan

Hi Heshan,

After I showed you how to build the plan and execute it yesterday, have you started looking at it? Do you think you will manage?

Maybe someone else here on rdf4j develop knows of a good resource for understanding the volcano model and iterators as well as how to generate a plan from an AST???
