Odyssey roadmap: what else do we want from the connection puller. Andrey Borodin



The report Andrei Borodin tell how they have taken into account PgBouncer scaling experience in the design of compounds puller Odyssey as it rolled out into production. In addition, we will discuss what functions of the puller we would like to see in new versions: it is important for us not only to cover our needs, but to develop the Odyssey user community .

Hello! My name is Andrey.





At Yandex, I am developing open source databases. And today we have a topic about connection pooler connections.





If you know how to call connection pooler in Russian, then tell me. I really want to find a good technical term that should be established in the technical literature.
