Pairing Data according to criteria - Dictionary

[Yna_Db]

I did not replicate this situation but to me, a Dictionary.ByKeysValues node (spring nodes) makes sense here: Walls have a tag (=keys) to identify elements in Excel sheet (=values), and you need to search by ‘Pier Number’ (=search keys). See in the thread you mentioned:

LOGIC If value matches a value in a dictionary , append associated value

The “Dictionary.ByKeysValues” node from spring nodes makes an actual dictionary and should perform much faster for large data sets. (because evaluations are not free) [DynamoSandbox_2016-01-30_10-34-29]
