Introduction to the Event and Guest Speaker [00:00:01 - 00:02:57]
Brief Description: The host welcomes the audience to the event at Brian Park stage and introduces the guest speaker, Garaudy Etienne, a lead product manager at MongoDB. The audience is excited to learn about various scaling strategies.

The Importance of Scaling Databases [00:02:58 - 00:05:56]
Brief Description: Garaudy explains why scaling databases is crucial, focusing on the need for CPU power, RAM for fast data access, disk throughput, and storage capacity as databases grow and more users come on board.

Vertical Scaling Strategy [00:05:57 - 00:10:06]
Brief Description: The concept of vertical scaling is discussed, where a single machine is upgraded to handle increased load. The simplicity of this approach is highlighted, along with its limitations, such as cost and the physical limits of machine size.

Horizontal Scaling with Sharded Collections [00:10:07 - 00:20:08]
Brief Description: Garaudy shifts to horizontal scaling, detailing how MongoDB uses sharded collections to distribute data across multiple machines. He explains the process of sharding, the importance of choosing a good shard key, and the benefits of linear growth in resources.

Introducing a New Horizontal Scaling Option [00:20:09 - 00:28:56]
Brief Description: A new horizontal scaling option is introduced, which allows for moving unsharded collections across shards without the need for sharding each collection. This simplifies the scaling process and requires no application changes.

Unsharding Collections and Concluding Thoughts [00:28:57 - 00:35:28]
Brief Description: The presentation concludes with the introduction of the ability to unshard collections, allowing previously sharded collections to be consolidated onto a single shard. Garaudy emphasizes the goal of MongoDB to simplify scaling decisions for users until it's necessary to shard collections.
