Summary: This is Ruby's project to implement load balancer support. Engineer(s): Oleg Pudeyev, Dmitry Rybakov 2021-08-11: Setting target date to 2021-08-27 Oleg has returned from PTO and he and Dmitry had been tag-teaming progress before Dmitry went on PTO. Oleg is now proceeding through the final tickets in the epic, after which we will focus on ensuring quality and stability before we tag a release. Engineer(s): Oleg Pudeyev, Dmitry Rybakov 2021-07-14: Setting target date to 2021-08-20 A valiant effort was made to complete this work in time for the 2.15 release on July 14th. Since it was down to the wire the team decided to release a cut of the driver sans load balancer with the intention to follow up with another minor release in the near future. Oleg is currently on vacation for 2 weeks, returning next week. While he is away, Dmitry has picked up this work to continue progress. When Oleg returns they we will be all hands on completing this work. Engineer(s): Oleg Pudeyev Cost in Eng Weeks: 5 Original | 8 to date | 10 Est Final 2021-07-14: Setting target date to 2021-08-06 Oleg has continued making excellent progress through this dense epic and we are approaching the home stretch. A valiant effort was made to complete this work in time for the 2.15 release on July 14th. Since it was down to the wire the team decided to release a cut of the driver sans load balancer with the intention to follow up with another minor release in the near future. Oleg is going on vacation in the upcoming weeks, so if this does not wrap in the next two days it will be on pause until he returns the week of August 2nd. Engineer(s): Oleg Pudeyev Cost in Eng Weeks: 5 Original | 6 to date | 8 Est Final 2021-06-30: Setting target date to 2021-07-23 Oleg continues to chew through tickets in this epic at a strong pace. This implementation is quite significant and there are a number of tickets remaining on top of the plethora of already completed work. Oleg is going on vacation in the upcoming weeks, so it is beginning to look like we will not have load balancer at the time of the 5.0 announcement. Given the functional requirement for load balancer, we will therefore likely be tagging our compat release one to two weeks following 5.0.

Currently in progress are the implementation of useMultipleMongoses on the client level in the unified test runner ( RUBY-2646 ) as well as implementing connect=load_balanced ( RUBY-2647 ). On the horizon are several tickets to address pinning cursors and transactions to connections. Currently projecting on par with original effort estimation.
