It allows you to <\/span><b>develop insight-driven applications<\/b><span style=\"font-weight: 400\"> quickly and easily using the same SDKs. It removes the need for ETL and the complexity of managing a separate analytics system. Couchbase\u2019s 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. <\/span><a href=\"https:\/\/developer.couchbase.com\/documentation\/server\/5.5\/analytics\/introduction.html\"><span style=\"font-weight: 400\">Read more&#8230;<\/span><\/a><\/p>\n<h2><b>Unmatched agility and flexibility<\/b><\/h2>\n<h3><b>ANSI joins in N1QL<\/b><\/h3>\n<p><span style=\"font-weight: 400\">The Couchbase Data Platform is the only platform that extends SQL to support JSON data natively via N1QL queries. N1QL now has support for ANSI joins making it easier to <\/span><b>migrate applications<\/b><span style=\"font-weight: 400\"> from RDBMS to Couchbase. Developers are also more productive as they can <\/span><b>leverage their SQL knowledge<\/b><span style=\"font-weight: 400\"> to develop applications on Couchbase. <\/span><\/p>\n<p><span style=\"font-weight: 400\">Here is the kind of JOIN syntax you are used to using, which is now available in Couchbase:<\/span><\/p>\n<pre class=\"lang:default decode:true\">SELECT DISTINCT route.destinationairport\r\nFROM `travel-sample` airport \r\nJOIN `travel-sample` route\r\nON airport.faa = route.sourceairport\r\nAND route.type = \"route\"<\/pre>\n<p><span style=\"font-weight: 400\">ANSI joins support <\/span><b>improves data modeling<\/b><span style=\"font-weight: 400\"> capability and flexibility with Couchbase. Since you can join based on arbitrarily complex expressions, business requirements can be coded and translated effectively and efficiently. We&#8217;ve extended ANSI syntax to join on both scalars and arrays. <\/span><a href=\"https:\/\/www.couchbase.com\/blog\/ansi-join-support-n1ql\/\"><span style=\"font-weight: 400\">Read more about ANSI join support &#8230;<\/span><\/a>\u00a0and a technical overview of <a href=\"https:\/\/www.couchbase.com\/blog\/new-querying-features-couchbase-server\/\">New Querying Features in Couchbase 5.5<\/a>.<\/p>\n<h2><b>Unparalleled performance at scale<\/b><\/h2>\n<h3><b>Aggregate optimization<\/b><\/h3>\n<p><span style=\"font-weight: 400\">One of the key advantages of a declarative query language like N1QL is that the system can optimize and improve the query plans and execution without changing the applications. Since the introduction of N1QL, Couchbase has improved the query performance by <\/span><b>orders of magnitude,<\/b><span style=\"font-weight: 400\"> and with aggregate optimization, the query engine leverages the indexes to perform aggregate calculations to improve the performance of queries by another order of magnitude. <\/span><b>Your existing aggregate queries, with matching indexes, will simply run faster.\u00a0 <\/b>Read &#8220;<a href=\"https:\/\/www.couchbase.com\/blog\/new-querying-features-couchbase-server\/\">New Querying Features In Couchbase 5.5<\/a>&#8220;.<\/p>\n<h3><b>Index partitioning<\/b><\/h3>\n<p><span style=\"font-weight: 400\">With support for index partitioning, you can now index a large number of documents and horizontally scale out an index as needed. The system will partition the index <\/span><b>across a number of index nodes<\/b><span style=\"font-weight: 400\"> using hash partitioning. Index partitioning is transparent to queries \u2013 one does not have to update the queries when changing the index partitioning strategy.<\/span><\/p>\n<p><strong>Read more<\/strong> about new Index Service features <a href=\"https:\/\/www.couchbase.com\/blog\/index-service-couchbase-server-5-5\/\">in general here<\/a> and about <a href=\"https:\/\/www.couchbase.com\/blog\/index-partitioning-couchbase-server\/\">Index Partitioning in detail\u00a0here<\/a>.<\/p>\n<h3><b>Data compression<\/b><\/h3>\n<p><span style=\"font-weight: 400\">With end-to-end compression from client to storage, Couchbase significantly <\/span><b>reduces the cost of network, memory, and storage<\/b><span style=\"font-weight: 400\"> required for your existing workloads. Documents are transparently compressed when transferred between the clients and the servers, in the server cache, and on disk.

Couchbase enhances the detection of common disk failures and <\/span><b>automatically fails over<\/b><span style=\"font-weight: 400\"> the node with bad disks saving operators time and energy. It also handles multiple server failures based on the replica count to avoid data loss, and can fail over an entire server group if a rack or zone is not available.<\/span><\/p>\n<h3><b>Security compliance<\/b><\/h3>\n<p><span style=\"font-weight: 400\">Couchbase continues to extend its support for security to enable enterprises to meet increasing security compliance requirements such as the EU&#8217;s General Data Protection Regulation (GDPR) effective May 2018. We extend <\/span><a href=\"https:\/\/developer.couchbase.com\/documentation\/server\/5.5\/security\/security-certs-auth.html\"><b>X.509 certificate authentication<\/b><\/a><span style=\"font-weight: 400\"> beyond key-value data access to query and search services for all SDKs. <\/span><\/p>\n<p><span style=\"font-weight: 400\">We also support <\/span><b>field-level encryption<\/b><span style=\"font-weight: 400\"> in our SDKs to protect sensitive user data.

In your application you can set thresholds to allow you to log operations based on performance.\u00a0 You can correlate timing information from client through to server and back to quickly triage performance issues and <\/span><b>help identify the root cause<\/b><span style=\"font-weight: 400\"> of performance issues. The performance of operations are all exposed via methods you are already familiar with in the Couchbase SDK. \u00a0An upcoming blog will highlight these new features in more depth.<\/span><\/p>\n<h3><b>IPv6 support<\/b><\/h3>\n<p><span style=\"font-weight: 400\">With the explosion of mobile and IoT devices, enterprises are seeing an increasing percentage of their user traffic coming from IPv6. Many large enterprises are starting to deploy IPv6 infrastructure to support these IPv6 devices.
