“在我们的案例中,由于高吞吐量和低延迟的要求,DynamoDB无服务器并不是一个很好的选择。此外,不要低估硬件的作用。更好地利用硬件是降低成本同时提高性能的关键。” 迁移到GCP,获得更好的性能和更低的成本 Digital Turbine是移动广告技术领域的巨头,年收入达5亿美元,在其DynamoDB实施中面临着越来越大的挑战。虽然...
21. How is Amazon's NoSQL implementation different from other well-known ones like Cassandra or MongoDB? A managed NoSQL database service, DynamoDB provides quick, predictable performance with easy scalability. Several significant aspects set DynamoDB apart from other well-liked NoSQL implementations...
To avoid this problem, NoSQL databases require you to split up your data into smaller segments and perform all queries within one of these segments. This is common across all NoSQL databases. In DynamoDB and Cassandra, it's called apartition key. In MongoDB, it's called ashard key. The...
You may be interested in moving to a scalable, reliable NoSQL database platform like ScyllaDB, but aren’t sure which interface to use: our Apache Cassandra® compatible Cassandra Query Language (CQL) interface or our newer Amazon DynamoDB® compatible interface. Or maybe you are familiar ...
There are many well-known NoSQL databases available, including MongoDB, Cassandra, HBase, Redis, Amazon DynamoDB, and Riak. Each of these was built for a specific range of uses and will therefore offer different features. We could group these databases into the following categories: columnar ...
As a NoSQL DB, it is usually compared with Hadoop or MongoDB (DynamoDB vs. Hadoop vs. MongoDB).Picture credit : All Things Distributed.Features:Managed NoSQL database. Provisioned throughput. Fast, predictable performance. Fully distributed, fault tolerant. JSON support....
目前,Apache Cassandra和MongoDB是被使用最为广泛的NoSQL数据库。Atlas则是由MongoDB提供的DBaaS(数据库即服务)。不过,目前支持将RDBMS迁移到MongoDB或Cassandra的工具并不多。当然,我们也可以使用ETL工具或自定义的转换引擎,来实现此类复杂的迁移。 此外,由云服务提供商提供的专有数据库有:Azure Cosmos DB、AWS Dyn...
