Description
Apache Accumulo enables users to efficiently store and manage extensive data sets across a distributed cluster. It relies on Apache Hadoop's HDFS for data storage and utilizes Apache ZooKeeper to achieve consensus among nodes. While many users engage with Accumulo directly, it also serves as a foundational data store for various open-source projects. To gain deeper insights into Accumulo, you can explore the Accumulo tour, consult the user manual, and experiment with the provided example code. Should you have any inquiries, please do not hesitate to reach out to us. Accumulo features a programming mechanism known as Iterators, which allows for the modification of key/value pairs at different stages of the data management workflow. Each key/value pair within Accumulo is assigned a unique security label that restricts query outcomes based on user permissions. The system operates on a cluster configuration that can incorporate one or more HDFS instances, providing flexibility as data storage needs evolve. Additionally, nodes within the cluster can be dynamically added or removed in response to changes in the volume of data stored, enhancing scalability and resource management.
Description
Greetings! BergDB is an efficient database built on Java and .NET, crafted for developers who want to concentrate on their tasks without getting bogged down by database complexities. It features straightforward key-value storage, ACID-compliant transactions, the ability to perform historic queries, effective concurrency management, secondary indices, swift append-only storage, replication capabilities, and seamless object serialization among other attributes. As an embedded, open-source, document-oriented, schemaless NoSQL database, BergDB is purposefully designed to deliver rapid transaction processing. Importantly, it ensures that all database writes adhere to ACID transactions, maintaining the highest consistency level available, which is akin to the serializable isolation level in SQL. The functionality of historic queries is beneficial for retrieving previous data states and managing concurrency efficiently, as read operations in BergDB are executed without locking any resources, allowing for smooth and uninterrupted access to data. This unique approach ensures that developers can work more productively, leveraging BergDB’s robust features to enhance application performance.
