Is there any work around for indexing list in Apache ignite and use in where clause?

[Manikanta Reddy P]

I am not sure how to index List/array in apache ignite. I want to use my
list/array in where clause, I can write custom function but it will search
all the data set, But I am looking for indexing of list/array. Please help
me.

Thanks,
Mani.
