New features

Couchbase Analytics

    Couchbase Server 6.0 delivers the first production release of Couchbase Analytics. Our Analytics service enables you to analyze your JSON data in real time without the need to extract, transform, load (ETL) your data into a separate system. It allows you to develop insight-driven applications quickly and easily using the same SDKs.

Couchbase Server 6.0发布了Couchbase 分析的第一个产品版本。我们的分析服务允许您实时分析JSON数据，而不需要将数据提取、转换、加载(ETL)到单独的系统中。它允许您使用相同的sdk快速轻松地开发具有洞察力的应用程序。

    It supports hybrid operational and analytical processing (HOAP) workloads and allows NoSQL users to run ad hoc analytical queries leveraging a massively parallel processing (n MPP) query engine without impacting application performance.

    它支持混合操作和分析处理(HOAP)工作负载，并允许NoSQL用户利用大规模并行处理(n MPP)查询引擎运行特定的分析查询，而不会影响应用程序的性能。

    Couchbase’s unique architecture for Multi-Dimensional Scaling (MDS) allows operational and analytical queries to run concurrently without impacting one another, providing the workload isolation required for production deployments.

    Couchbase独特的多维伸缩体系结构(MDS)允许同时运行操作和分析查询，而不会相互影响，从而提供了生产部署所需的工作负载隔离。

N1QL for Analytics

    SQL++ builds on the popularity and power of the SQL standard. It is the language used for querying schemaless, semi-structured, JSON data found in the Couchbase Data Platform.

    SQL++基于SQL标准的流行和强大功能。它是用于查询Couchbase数据平台中的无模式、半结构化JSON数据的语言。

    Couchbase Server 6.0 brings the first commercial implementation of the SQL++ language and uses it in the new Analytics service.

    Couchbase Server 6.0带来了SQL++语言的第一个商业实现，并在新的分析服务中使用它。

For more information, see the N1QL for Analytics Language Reference.

Support for Timers in Couchbase Functions 在Couchbase函数中支持定时器

    This release adds support for timers in Couchbase Functions.

    Timers enable the ability to trigger routines at specific timestamps. They are constructs by which developers can specify logic routines that are to be triggered at a future time. By having them run directly in a Couchbase Service they’re close to your data and highly efficient.

    定时器能够在特定的时间戳触发例程。它们是开发人员可以指定逻辑例程的构造，这些逻辑例程将在将来某个时候触发。通过让它们直接运行在Couchbase服务中，它们接近您的数据并且非常高效。

For more information, see Timers.

Full-Text Search improvements

    The Full-Text Search indexing capabilities have been greatly improved. The indexing time has been cut in half and the index space requirements are as much as 70% lower. These new indexing features are on by default and upgrading is as simple as recreating the index using the new 6.0 index type option. For more information, see Creating Indexes.
