[07:30:48] <sinclair_> hey everyone, is there a way to filter for _id timestamps greater than some threshold?
[07:53:15] <pagios_> hello, reading about mongo transactions, if i get 2 read requests for a document field in a collection , AT THE SAME TIME, in a transaction one of them will wait for the first to finish and then get processed?
[08:05:43] <pagios_> i understand that a transacton makes multiple updates/operations ATOMIc, either they all fail or succeed. But my question is if i have multiple transaction IN different sessions, will those sessions block and wait for each other to get accurate values from DB ?
[08:13:45] <pagios_> for example transaction1 has read and update on field1, while transaction2 has a read and update on field1. How can i make sure transaction2 only reads after transaction1 completees OR bfore transaction1 completes?
