Hi people, I've been making a small project using Pharo and Voyage, and everything is going well, but I'm facing a performance issue when retrieving items from Mongo. I've two classes, one for items, and other for users, and both are Root. Each item contains the user who created it. My question is if there's a best way of querying all items for an user, using selectMany, when you have a document containing another. As work-around, by now, I'm making a selectAll and then filter them on memory, and that takes a lot of time and memory when the collection grows. Can you help on this? Thanks, Gonzalo -- View this message in context: http://forum.world.st/Voyage-selectMany-with-multiple-Root-tp4778705.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
