Inadequate storage memory, RAM and other operating parameters can drastically degrade the performance of a MongoDB. For instance, if the number of user connections is very large, it will hinder the ability of th
Monitoring MongoDB databases allows you to improve the performance of your application stack and optimize for costs by enabling you to: Understand the current capacity of your database Observe how utilized resources are Observe the presence of abnormal behavior and performance issues Detect and r...
Implementing parent document retrieval using MongoDB’s LangChain integration In this tutorial, we will implement parent document retrieval using MongoDB’s LangChain integration, and see how to use it in a RAG application as well as an AI agent. The Jupyter Notebook for this tutorial can be ...
To optimize query performance, you should create indexes on frequently queried fields: db.users.createIndex({tenantId:1,email:1},{unique:true})db.books.createIndex({tenantId:1,isbn:1},{unique:true})db.tenants.createIndex({subdomain:1},{unique:true}...
When using regular expressions, especially with a leading^, it’s important to be mindful of performance. MongoDB can efficiently use indexes for certain types of regex queries, but a leading^often prevents this optimization. If you’re performing frequent “starts with” queries, consider indexing...
Setting MongoDB as a VM on a hypervisor would let you scale up RAM and CPU cores later on. Amount of CPU cores and RAM that should be assigned depends on your infrastructure needs and budget. 3. Optimization The most useful tip is to optimize your database queries: ...
None of these things describe TokuMX, but it demonstrates that there are many schools of thought on how to optimize databases, and MongoDB in particular. I’d like to elaborate more on what TokuMX really is and how we built it. First, let’s talk about what MongoDB is. MongoDB consis...
MySQL, PostgreSQL, MongoDB, and the servers on which they run. PMM’s Query Analytics tool helps you quickly locate costly and slow-running queries so you can quickly address bottlenecks impacting performance. And remember that Percona engineers are always available to help you when you get ...
Using tools to determine which instances are using memory the most, and for what data, can help you to optimize your environment. Number of connections Database transactions are usually initiated by applications and processes through “connections.” The number of open connections can impact the per...
