MarkLogic now offers greater agility and flexibility to do more with data and content at a faster pace, while also making the best use of the new generation of cloud infrastructure – which is critical to organizations who are building powerful, mission-critical applications. With MarkLogic 7, our customers can gain more operational agility and adhere to operational standards for data governance, security, and availability – and give information applications more power.
New Feature Highlights
Aligning a storage strategy with the value and use of your data allows you to make smarter tradeoffs among cost, performance, and availability. You can implement a data governance policy and deploy MarkLogic using a fluid mix of SSD, local disk, shared disk, and the Hadoop Distributed File System (HDFS) as well as Amazon EBS and S3. MarkLogic lets you easily and consistently move data between tiers without complicated and expensive ETL and data duplication.
MarkLogic Runs on HDFS
Use Hadoop as a shared file system (HDFS), storage tier (HDFS), or in mixed batch (MapReduce) and real-time workloads. You get a drop-in enterprise database for real-time search, delivery, and analytics, and can leverage existing Hadoop investment without compromising enterprise capabilities (security, HA/DR, transactions).
MarkLogic Runs on Amazon S3
MarkLogic also supports Amazon S3 (Simple Storage Service) as a shared file system or storage tier. You can easily backup any MarkLogic database to S3 – just enter your AWS credentials to MarkLogic and make the backup location an S3 bucket.
MarkLogic-supported Amazon Machine Images (AMIs), CloudFormation Templates, and Orchestration tools make it easy for you to build, scale, rebalance, and even remove clusters. MarkLogic provides an integrated solution that includes guidelines, scripts and tools that help support "Managed Clusters" on AWS or other cloud environments.
You need elasticity to ensure your infrastructure is sized correctly and can scale up or down as needed. This can help not only increase service levels but also decrease cost, by most effectively using shared resources like in a cloud environment. MarkLogic’s online rebalancing automatically manages compute and storage loads across a system even as business requirements change, allowing for dynamic changes – without downtime – to the system with full transactional guarantees for mission-critical applications.
Cluster Monitoring Tools
Get better performance and make better use of resources by better understanding the behavior of your system. In the event of system problems, MarkLogic cluster monitoring helps you more effectively identify patterns and more quickly diagnose outliers. A new admin dashboard with performance charts and statistics, plus a monitoring API, lets you drill down and filter sets of resources and charts, making it easy to compare and spot exceptions.
Configuration Management Enhancements
Configuration and deployment management helps users replicate or move configurations associated with a particular application across different environments. Moving applications to different environments is now easier and more reliable, and MarkLogic provides an audit trail for tracing and rolling back changes across a cluster.
MarkLogic Goes Green…Requiring Less Disk Space
We continue to look for ways to improve efficiency of our platform. Current MarkLogic customers will see that MarkLogic 7 requires anywhere from 33% to 60% less disk, compared to previous versions. This saves money for hardware, energy, licensing, and other management expenses.
Semantics allows users to find, share, and combine information in a way that was previously difficult – if not impossible. MarkLogic Semantics provides powerful new capabilities that previously had to be supplied by add-on products—if they were achievable at all. MarkLogic can now store and query data in RDF format using SPARQL syntax. RDF allows customers to establish relationships between pieces of information (subject, predicate, object), while SPARQL is a query language that lets users interrogate or infer those relationships.
Search enhancements in MarkLogic 7 allow customers to use MarkLogic as a full-fledged Enterprise Search solution. Users get better search results as well as more granularity and control over searches via new features such as relevance scoring for range queries, custom tokenization, and path range indexes.
REST & Java API Improvements
Improvements to the REST and Java APIs make their application simpler to understand and easier to use, helping to flatten the learning curve and get developers productive more quickly. Additionally, the APIs have been extended to include functions to automate deployment of code and configuration between environments.
Fast data Ingestion
MarkLogic enables fast loading for all your data types including semantic triples. You can load data from your laptop or in parallel across a cluster enterprise-wide.
Security (LDAP / Kerberos)
You can now set up MarkLogic to utilize existing identity management services for authentication and authorization, and enable single-sign on using Kerberos. This centralizes identity management to allow greater enterprise-level control and ease compliance tasks, removes the need for IT to maintain disparate identity management services, and also reduces login and password burden on users.
