Feed: Blog – OrientDB. Author: Leann. The power of graph database solutions means that creating data and finding relationships between data sets is not constrained by defined data classifications, formats, storage locations or original data structure.By storing and monitoring relationship data, graph solutions enable organizations to act on changes to their data model without the limitations of a set database structure, known as schemas. A database that isn’t limited to one schema type also simplifies data modeling and querying of connected data. Although graph solutions support schema-less use, you might still want to use a schema to enforce some structure ... Read More

Feed: Blog – OrientDB. Author: Leann. Developers have always had to do more with less. What the OrientDB team has loved about working with developers over the last eight years is learning all the ways in which they’ve innovated around complex data challenges even as data types, formats and application usage have changed.When OrientDB founder Luca Garulli created our database management system, he wanted to empower developers’ unsung innovation by freeing them from the chains of monolithic data formats and use. His mission was to create a high-performance transaction graph database that enables developers to: Find new, complex relationships between ... Read More

Feed: Blog – ArangoDB. Author: Simon Grätzer. With ArangoDB 3.4 we finally made the rocksdb storage engine the default. This decision was made after a year of constant improvements to the engine to make it suitable for all our customer’s use cases. Improved Read / Write-Performance We massively improved the binary on-disk storage format with the 3.4 release. This format allows inserting new documents in an order that RocksDB prefers. Using the new format will reduce the number of compactions that RocksDB needs to do for the ArangoDB documents stored, allowing for better long-term insertion performance. The sustained insertion performance ... Read More

What if average citizens were able to quickly experiment with public government spending data to determine whether any officials were misusing taxpayer funds?That’s the question Gabriel Mesquita, a software developer and computer scientist from Brazil, recently set out to answer. In a post on Hacker Noon, Mesquita explored whether any Brazilian government officials were using their monthly allowances illegally by buying products and services from companies owned by people they know.   In his experimental attempt to detect fraudulent patterns in spending, he turned to OrientDB, the world’s fastest NoSQL database. A Data Model ... Read More

Author: Kaveh Vahedipour. “I must have a prodigious amount of mind;it takes me as much as a week, sometimes, to make it up!”― Mark Twain How many shards should one choose, when creating collections in ArangoDB clusters? TLDR: Don’t be too shy with sharding your data in many shards across your cluster. Be mindful however that AQL-heavy applications might not profit as much from heavy distribution. How a database works and performs in a single instance setup is becoming more and more irrelevant lately, if said database cannot scale. Distributed, clustered databases are, as far as ... Read More

Feed: Blog – ArangoDB. Author: Max Neunhöffer. This post uses the new .tar.gz binary distribution of ArangoDB to run multiple versions of ArangoDB alongside each other on the same machines. We will do a production-ready deployment on 3 cloud instances with authentication, TLS encryption, (self-signed) certificates and systemd service. In the end, we show how to perform a rolling upgrade for one of the clusters to a new version. The new .tar.gz binary archive Starting with Version 3.4.0 we have changed the way how we build our binary distribution. We are now using completely static binaries (see here for another ...

Feed: Blog – ArangoDB. Author: Willi Goesgens. When using a database like ArangoDB it is also important to explore how it behaves once it reaches system bottlenecks, or which KPIs (Key Performance Indicators) it can achieve in your benchmarks under certain limitations. One can achieve this by torturing the system by effectively saturating the resources using random processes. This however will drown your system effectively – it may hinder you from capturing statistics, do debugging, and all other sorts of things you’re used to from a normally running system. The more clever way is to tell your system to limit ... Read More
