Implement Summapfiltered in Order to Be Able to Limit the Number of Keys for Which Values Will Be Summed by Summap
ImplementsumMapFilteredin order to be able to limit the number of keys for which values will be summed bysumMap. #4129 (Léo Ercolanelli)
Why it matters
To provide users with the ability to restrict the aggregation to specific keys when using map-based summation, reducing overhead and focusing the aggregation on relevant data keys.How to use it
Use thesumMapFiltered function in your queries by specifying a filter condition that limits the keys to be included in the sum. This works similarly to sumMap but applies filtering to the keys beforehand.
