Or in other words, the aggregation pipeline is a multi-stage pipeline, so in each state, the documents taken as input and produce the resultant set of documents now in the next stage(id available) the resultant documents taken as input and produce output, this process is going on till the last stage. In MongoDB, the aggregation pipeline consists of stages and each stage transforms the document. MongoDB provides three ways to perform aggregation It is similar to the aggregate function of SQL. It collects values from various documents and groups them together and then performs different types of operations on that grouped data like sum, average, minimum, maximum, etc to return a computed result. In MongoDB, aggregation operations process the data records/documents and return computed results.

In my case, I have taken an already present startup_log collection in my ‘local’ dataset in MongoDB local server. Let’s look at MongoDB Compass and make a simple pipeline. Please have a look before moving further. In case you don’t know about MongoDB compass and how we use it along with python, here is another article I wrote for just this purpose.
From my personal experience, this integration is extremely helpful.
MONGODB COMPASS GROUP BY HOW TO
In this article, I will show you how to use these aggregate pipelines in MongoDB compass and use these pipelines inside our python code. So, in terms of MongoDB, we can add various functions on top of each other as separate elements and form a more refined and complicated function that does the job easily and with a single step. Why don’t we start with the meaning of Aggregation?Īggregation: According to formal definitions, it is a process of forming or calculating an element by the combination of several separate elements. So, in terms of these defined stages, the scope of the article would lie in the data category which makes the complete process of MLOps much more systematic, faster, and flexible. Deployment: Deploy in production, monitor, and maintain the system. Modeling: Select and train model, perform error analysis on it.Ĥ.
Data: Define data and establish baseline, label and organize data, feature extraction, data validation and etc.ģ. Scoping: Defining your project, target users and a plan for how you are gonna carry a project.Ģ. Steps for MLOps are divided into 4 general categories:ġ. Such pipelines have a big contribution in exercising good MLOps practices, automating the process of data manipulation, and importing the data to feed into the network with the work of the pipeline. Today, we will look at a very powerful functionality that is available to us when working with NoSQL data in the MongoDB database. So, definitely knowing how to store, manipulate, ingest and import data is critical for any relative field practitioner. For data science and machine learning, we need data and without it, both domains cannot even exist to be applied. Whatever we do, if we know multiple tools for various tasks that we might have to perform then it’s an extremely useful set of knowledge. “Working smart and having utilities is always a great skill to have”
