MongoDB is strongly consistent by default as all read/writes go to the primary in a MongoDB replica set, scaled across multiple partitions (shards). Amazon DynamoDB is a popular NoSQL database choice for mid-to-large enterprises. An item or record cannot exceed 400KB. Users can enforce checks on document structure, data types, data ranges and the presence of mandatory fields. The MongoDB platform can be used by developers building transactional, operational,...

MongoDB database server: Server-Side Public License (SSPL) . July 10, 2018 . This flexible data model makes it easy for developers to represent hierarchical relationships and other more complex structures. Get started with SkySQL today! In this section we will again compare DynamoDB with its closest analog from MongoDB, Inc., MongoDB Atlas. The founders originally focused on building a platform as a service using entirely open source components, but when they struggled to find an existing database that could meet their requirements for building a service in the cloud, they began work on their own database system. Product packages like MongoDB Enterprise Advanced bundle operational tooling and visualization and performance optimization platforms with end-to-end security controls for applications managing sensitive data. DynamoDB does not have native data validation capabilities. The basic difference between MongoDB and DynamoDB is that DynamoDB is a NoSQL database service used on AWS console whereas MongoDB is a Database Application. Founder & CTO. Compared to MongoDB, DynamoDB has limited support for different data types. Like all Amazon product offerings, read and … In this post, we saw how DynamoDB compares to MongoDB. While provisioning is simple, other key operational tasks are lacking when compared to MongoDB: Fewer than 20 database metrics are reported by AWS Cloudwatch, which limits visibility into real-time database behavior, AWS CloudTrail can be used to create audit trails, but it only tracks a small subset of DDL (administrative) actions to the database, not all user access to individual tables or records, DynamoDB has limited tooling to allow developers and/or DBAs to optimize performance by visualizing schema or graphically profiling query performance, DynamoDB supports cross region replication with multi-primary global tables, however these add further application complexity and cost, with eventual consistency, risks of data loss due to write conflicts between regions, and no automatic client failover. In this article, we will compare two database systems and help with pointers that one should keep in mind while deciding on which database to use for your applications. Many concepts in DynamoDB have close analogs in MongoDB. Thermo Fisher migrated from DynamoDB to MongoDB, If accessing a JSON object, the entire document must be retrieved, even if the application needs to read only a single element. Although schema-free, documents of the same collection often follow the same structure. 5. DynamoDB has a more hands-off operations model than MongoDB as you don't think to think about instances and scaling up or down. MongoDB's query language enables developers to build applications that can query and analyze their data in multiple ways – by single keys, ranges, faceted search, graph traversals, JOINs and geospatial queries through to complex aggregations, returning responses in milliseconds. Is there an option to define some or all structures to be held in-memory only. Similarly data restored from backups may not be transactionally consistent with the original table. Graph Database Leader for AI Knowledge Graph SkySQL, the ultimate MariaDB cloud, is here. Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. MongoDB allows reads and writes against the same documents and fields within the transaction. Around the same time, Amazon found that its developers enjoyed using SimpleDB, its primary NoSQL database service at the time which allowed users to offload database administration work. It is key to point out from the list above that indexes affect pricing and strongly consistent reads are twice as expensive. DynamoDB may work for organizations that are: Looking for a database to support relatively simple key-value workloads, Heavily invested in AWS with no plans to change their deployment environment in the future. Indexes can be defined as hash or hash-range indexes; more advanced indexing strategies are not supported. But SimpleDB, which is no longer being updated by Amazon, had severe limitations when it came to scale; its strict storage limitation of 10 GB and the limited number of operations it could support per second made it only viable for small workloads. Commercial licenses are also available. Whether clusters will be replicated across multiple regions. In summer of 2016, MongoDB Atlas, the MongoDB fully managed cloud database service, was announced. Please select another system to include it in the comparison. MongoDB available as DBaaS (MongoDB Atlas). Both are widely deployed and deliver highly-scalable, cloud-level performance. Below, we’ve highlighted some of the key performance capabilities that support mission-critical applications.
