Consequently, several business owners worldwide are inclined towards analytical solutions to enhance their decision-making capacities based on data-driven strategies. Additionally, because of digitalization, there is a growing necessity to systematize business processes to boost market growth further. Data analytics are able to automate business processes and use optimization techniques to predict various business process outcomes. This is achievable with the aid of the two well-known NoSQL database services available in the industry: AWS DynamoDB vs MongoDB. How do you differentiate between them? Whether you are a small team bootstrapping a proof of concept or an established one struggling with high throughput, pricing, and heavy loads, this post will serve as a guideline as well as compare MongoDB vs. Postgresql to help you choose the best for your data engineering database.
Overview
DynamoDB is a great database choice for situations where the amount of work is hard to predict. If you can figure out your application’s data access habits ahead of time and they don’t change too much, using DynamoDB will give you faster query times. But if you already use a lot of AWS services, the native integrations, especially with Step Functions, make it the best pick. In the same way, MongoDB is perfect if you need to store a lot of binary data or if your app needs geospatial queries.
AWS Dynamodb vs Mongodb
Both MongoDB and DynamoDB are reliable NoSQL databases that can meet a wide range of customer requirements. When choosing the most suitable solution, however, great analysis is needed. But if all of the necessary capabilities and functionality are available in the DynamoDB world, it’s an obvious choice to use the AWS native NoSQL solution.
AWS Dynamodb vs MongoDB: Factors To Consider
Neither of these possibilities applies to everyone, so more research is needed. Here are some points to think about:
#1. Skill Level
To begin, you need to evaluate the skill level of your team members and take into consideration the following:
- Will they be successful in running MongoDB?
- Can they guarantee that it operates faultlessly around the clock?
However, if you answered “no” to any of these questions, DynamoDB is worth investigating further.
#2. Speed
Think about how much speed you need for your application and how flexible you can be with data consistency. Which is more problematic, waiting a few extra seconds for the correct response, or receiving inaccurate information?
#3. Complexity
The final step is to estimate the difficulty of your query. You can get by with DynamoDB instead of MongoDB if your program doesn’t need to run complicated queries.
#4. Lock-In of Vendors
DynamoDB usage could result in being tied to a single provider. Since AWS employs a proprietary database model, migrating to a different cloud provider would necessitate a substantial investment in designing a new database system. Furthermore, it is difficult to concentrate on a multi-cloud approach if you have become reliant on several AWS services.
AWS Dynamodb vs Mongodb: Differences
While DynamoDB and MongoDB aim to solve the same problem by storing data in a NoSQL fashion, they approach that goal differently. Let’s look at the main differences between them that you need to be aware of to make the right choice for you or your business in terms of:
#1. Data Model
The BSON format is similar to JSON, and it lets MongoDB store dates, timestamps, 64-bit numbers, and decimal 128. GridFS holds more assets than MongoDB, which has a maximum document size of 16 MB. While DynamoDB is a key-value store that works with JSON. It uses document-like data structures that are more like program code objects. There are no files or documents over 400 kilobytes in size.
#2. AWS Native Integrations
You can set up MongoDB to run on any platform, whether it’s a laptop, a container, an on-premises server, or the cloud. In contrast, AWS is required for both the setup and operation of DynamoDB. As a native AWS application, DynamoDB works more closely with other AWS tools and services. ( AWS Dynamodb vs Mongodb).
#3. Querying Data & Indexes
MongoDB offers more flexibility in querying data as it allows users to aggregate and query data natively in multiple ways, such as:
- Single keys
- Ranges
- Graph traversals
- JOINs
On the contrary, DynamoDB natively supports only key-value queries yet allows users to carry out difficult aggregations using other AWS services such as Amazon Redshift and Elastic MapReduce. However, using these different services increases:
- Cost
- Latency
- Complexity
#4. Database backup & Recovery
The AWS service DynamoDB includes out-of-the-box support for Multi-Region and Multi-AZ data replication. This implies that a point-in-time restore can be performed either manually or automatically (on a continuous basis). In addition, you can easily set up backups with AWS products like “AWS Backup” and keep them in the cloud. While Dynamodb requires more configurations than MongoDB to get everything properly configured.
#5. Programming Language
MongoDB is written in C++ and supports programming languages like C, C++, Go, Java, JavaScript, PHP, Perl, Ruby, Python, and more. While DynamoDB supports programming languages like Java, JavaScript, Node.js,.NET, PHP, and more. ( AWS Dynamodb vs Mongodb ).
Mongodb vs Postgresql
As a smart reader should already know, the real question is not MongoDB vs. Postgres, but the best document database vs. the best relational database. This means, MongoDB is the way to go if you need a distributed database for current transactional and analytical applications that work with data that changes quickly and has different structures.
But, if a SQL database fits your needs, PostgreSQL is a great choice. In other words, what you are trying to do will determine the best answer for you. The goal of this piece is to help you understand the personality features and differences of each database so you can decide if it meets your needs.
Mongodb vs. Postgresql: Differences
Now that you know both technologies, let’s answer the MongoDB vs. PostgreSQL question. The selection must be made based on the company requirements, budget, and characteristics given below. These considerations influence the MongoDB vs. PostgreSQL choice:
#1. Definition
MongoDB is a schema-free NoSQL database that processes JSON data with optional models. It differs from the normal RDMS in syntax and structure. Built by MongoDB Inc. While, PostgreSQL, usually known as Postgres, is a free, open-source RDBMS. The University of California, Berkeley, developed it, and on July 8, 1996, it was made available to the public. It replaced the Ignes database. In PostgreSQL, Structured objects are used to store data instead of documents. Where the traditional SQL syntax and format are applied.
#2. ACID Compliance
MongoDB has the ability to be ACID-compliant, but PostgreSQL already has this feature built-in. The ACID properties are the most important parts of databases because they make it possible to keep track of events. ( Mongodb vs Postgresql ).
#3. Extensibility
Extensibility is simply the ability to add new features or functions. PostgreSQL allows extensibility in a number of ways, including through stored functions and procedures. Hence, the catalog-driven processes of PostgreSQL give it a wide range of uses. On the other hand, MongoDB now lets users develop and use their own functions. User-defined functions (UDF) allow users of relational databases like PostgreSQL to enhance SQL statements.
#4. Indexing
A disk index maps column values to their physical locations. The efficiency of database data retrieval procedures is increased. MongoDB uses indexes to speed up queries. Both the field and collection levels can be indexed. It offers B-tree, compound, text, geographical, hashed, and clustered indexes. while PostgreSQL also provides GIN, GiST, and Sp-GiST index types. The create index command defaults to a B-tree index.
#5. Language & Syntax
Both PostgreSQL and MongoDB support multiple languages. Python, R, Java, Scala, C, C++, C#, Node.js, and others are among the most popular database languages MongoDB supports. All applications perform well and scale well with MongoDB’s libraries and drivers, which handle all database functionalities. PostgreSQL, on the other hand, supports PL/pgSQL, PL/Python, PL/Perl, and PL/Tcl. Non-SQL procedural languages like PL/Java, PL/PHP, and PL/Ruby are supported.
#6. Data Maintenance
MongoDB uses Redundant Replica Sets to maintain data. These sets let you record and playback as needed. MongoDB also uses synchronous replication, which is when different repositories or systems update at the same time. To maintain its data, PostgreSQL uses 2-safe replication. This way, PostgreSQL can update both records at the same time, thus reducing the number of mistakes and keeping a complete and accurate backup.
Dynamodb vs. MongoDB Pricing
DynamoDB and MongoDB are two good NoSQL systems. Both serve business needs. Though DynamoDB starts out cheaper, security, table setup, and upkeep are easy. MongoDB also provides index validation, indexing strategies, query operations, and other data types. But its pricing is more expensive. Consequently, your needs, pricing budget, long-term spending, and programming experience will determine the choice. Thus, the best way to find out is to try the free trials of both before making a choice. To help you, in this section, we will again compare the pricing of DynamoDB vs. MongoDB.
Dynamodb vs. MongoDB Pricing: In Details
The pricing model for DynamoDB is based on throughput. Where users pay for a certain number of reads or writes on a given table, and AWS automatically slows down any reads or writes that go over that number. In theory, this sounds easy, but in practice, it’s much harder to estimate pricing and throughput properly.
Dynamodb vs. MongoDB Pricing: Factor Affecting It
Below is a list of all the things that could affect the price of operating DynamoDB:
- Size of the data per month
- size of each item
- Number of reads per second (pricing is based on “read capacity units,” which is equal to reading a 4KB object)
- When accessing a JSON object, the entire document must be retrieved, even if the program only needs to read one element.
- Number of Writes Per Second (Pricing is based on “Write Capacity Units,” which are the equivalent of writing a 1KB object.)
- Whether deals will be used or not
- Whether or not the clusters will be replicated across different regions
- Costs for backing up and restoring data
- Every month, data goes in and out of the database.
- Cross-regional operations require data transfers between regions, EC2 instances, and SQS queues.
- Use of more AWS services to fill in the gaps left by DynamoDB’s narrow key-value query model
- Number of data sent to CloudWatch for monitoring
- Number of database inspection events pushed into CloudTrail
From all indications, it is necessary to point out from the list above that indexes affect pricing, and strongly consistent reads are twice as expensive. Compared to DynamoDB, pricing for MongoDB is moderately specific by selecting just:
- The instance size should have enough RAM to accommodate the portion of your data (including indexes) that clients access most often
- The number of replicas and shards that will make up the cluster
- Whether to include fully managed backups
- The region(s) the cluster needs to run in
Additionally, users can adjust any of these parameters on demand. The only additional charge is for data transfer costs. Also, Luckily, both databases have free tiers where you can experiment with the settings that make sense for your use case. ( Dynamodb vs. MongoDB Pricing ).
