Gabriel Ciciliani (Pythian) delivers the talk, "Performing MongoDB Massive Write Operations Efficiently", on DAY 1 of the Percona Live Open Source Database Conference 2019, 5/29, at Austin, TX.
Either because of a new feature, a bug, or just for archival purposes, it is often necessary to update or remove large amounts of documents in production.
The challenge with this type of operation is not only to design an efficient process query-wise, but to be able to execute it in production without debilitating the servers or causing secondaries to lag.
There are strategies that can be used to create highly controlled write processes that could run for days under the radar, getting the job done without greatly impacting your application's performance.
In this session, I'm going to share with you key points to consider when creating massive write operations in MongoDB, examples of real-life processes executed, and a few lessons learned.
