Hello All, I need to 1) Look up some values from a source and cache them in a bolt 2) Filter a second stream based on the looked up values in (1).
Example: 1) Area Codes = 712, 915 -- these area codes might change from time to time 2) People living in different addresses Emit: People leaving in area codes 712 and 915 I want to use bolts (not trident). I've been reading about in-bolt caching to hold the looked up values but I am not sure how to utilize it in this context and I am also not sure how a database join would work in this context. Does someone have an example dealing with a similar use case? thanks, Clay
