This article introduces the latest features and improvements in ApsaraDB for MongoDB 7.0 and its advantages for your business.

By Zhongli, Feiyou and Yuanyi

Alibaba Cloud ApsaraDB for MongoDB 7.0 has arrived with a suite of innovative features and notable improvements, designed to enhance performance, bolster data management capabilities, and provide developers with a more extensive and flexible set of tools. Whether it’s managing vast datasets, performing real-time analytics, or building high-performance applications, Alibaba Cloud ApsaraDB for MongoDB 7.0 stands out as a choice worth looking forward to and trusting.

Why MongoDB 7.0?

1. Enhanced Functionality

Shard Key Analyzer: Starting from version 7.0, MongoDB supports analyzing the rationality of collection shard keys based on the results of sampled queries, which can help you better design your schema and shard keys, and make more efficient use of the sharding architecture.

ChangeStream for Large Change Events: The new $changeStreamSplitLargeEvent operator, introduced in version 7.0, enables splitting of change events exceeding 16 MB. This solves past limitations where changeStream couldn't support large change events.

2. Stronger Data Security

Queryable Encryption: Queryable Encryption is previously a preview feature in MongoDB 6.0, and now be ready for prime time in MongoDB 7.0, offering you an unparalleled level of protection for your most sensitive information. With this groundbreaking technology, your data stays encrypted at every stage of its lifecycle and can be decrypted only on the client-side without the server having knowledge of the data it's processing. This feature offers robust, comprehensive security and effectively counters the risks of data breaches.

User Roles System Variable: The USER_ROLES system variable in MongoDB 7.0 enables the retrieval of the current user's roles, providing a mechanism for role-based access control directly within the database. This feature is particularly beneficial for scenarios where documents contain sensitive information that should be accessible only to users with specific roles.

3. Greater Reliability and Stability

Metadata Consistency Checker: In previous versions of MongoDB, there were potential issues with inconsistencies in routing data or indexes. The MongoDB 7.0 release introduces the checkMetadataConsistency command, which checks for inconsistencies in metadata across different shards. Incorporate this inspection into your routine operations and maintenance tasks to proactively and promptly detect potential risks of metadata/index inconsistencies following maintenance routines or events such as out-of-memory errors or failovers.

Dynamic Concurrent Storage Engine Transactions(Read/Write Tickets): MongoDB 7.0 brings an exciting update that makes working with databases safer and more efficient than ever. The introduction of the Dynamic WiredTiger Tickets in MongoDB 7.0 automatically manages how many concurrent transactions (tickets) can happen at once within the WiredTiger storage engine, with the default value set at 128 tickets, optimizing performance. We strongly recommend adhering to this configuration for the time being. This dynamic control helps prevent the buildup of excessive requests that previously led to database slowdowns. By reducing the likelihood of these "avalanche" scenarios, MongoDB 7.0 ensures smoother operation, safeguarding your business from potential setbacks and maintaining continuous, reliable service for your customers.
