Couchbase Multi-Dimensional Scaling is breakthrough database technology that substantially increases application performance and dramatically reduces cost. Multi-Dimensional Scaling achieves these gains with the option to separate, isolate, and scale individual database services - query, index and data – allowing you to support more than one hardware profile so the resources can be optimized for a single service. The result is that you can run complex queries, create unlimited indexes, and continue to scale data across many nodes without worrying about performance suffering.
Other databases, such as MongoDB, Oracle, and Cassandra, have a limiting one size fits all approach to scaling that forces you to run every database service on every node. This approach leads to resource contention, slower performance, limited query capabilities, and overprovisioning. Couchbase Server 4.0 with Multi-dimensional Scaling removes all of these limitations, resulting in greater performance, at greater scale, all at a lower cost.
Why is Multi-dimensional Scaling Necessary?
While scaling a distributed architecture is great for data, it is a challenge for indexes and queries.
Simply put, scaling data speeds up reads and writes but it slows down queries, and while creating indexes speeds up queries it slows down writes. For example, if you scale out your database to support a massive amount of data, your query performance will suffer dramatically because the more nodes participating in a distributed query, the worse it performs. And creating many indexes to improve query performance will negatively impact write performance because writes do not complete until all indexes have been updated. The bottom line is that scaling out, with every database service running on every node, can result in a big drop in efficiency and performance.
How do Database Services Benefit from Isolation?
Queries require fast processors
If a query can be executed by a single node, or many queries by many nodes, the results will be returned faster, and it will not slow down reads and writes by monopolizing CPU time.
Indexes require high performance SSDs
If an index can be stored on a single node, or many indexes on many nodes, it can be searched faster, and it will not slow down writes by monopolizing disk IO.
Data is the whole reason for a distributed database
The more nodes you have, the more data you can store. These nodes benefit from increased memory but require less from the CPU and disk. When data is isolated from queries and indexes, read and write performance not only improves, it remains consistent.
How does Multi-Dimensional Scaling Work
Multi-dimensional Scaling allows you to separate and isolate database services - querying, indexing, and data - so you can scale and optimize the resources for each one based on its own individual workload.
– Your queries and indexes will perform better as they are no longer require every node.
– Your entire application will perform better as reads, writes, and queries will no longer compete for shared resources.
– Your hardware costs will decrease as you can apply bigger servers for queries and indexes, and smaller servers for data.
