Cassandra Query Language (CQL) You can read, write, update, and delete data from Cassandra by using the Cassandra Query Language (CQL). CQL is a flexible, SQL-like API that enables developers to execute data definition language (DDL) and data manipulation language (DML) statements. You use ...
A distributed database from Apache which is profoundly scalable and Cassandra is built to manage vast volumes of structured data. Cassandra gives excellent availability without any single failure. Cassandra is a database with NoSQL given by Apache. Within Cassandra the proven fault-tolerance and line...
Since every Cassandra node is capable of performing read and write operations, data is quickly replicated across hybrid cloud environments and geographies. If a node fails, users will be automatically routed to the nearest healthy node, leaving no single point of failure. They won’t even notice ...
Discover what is Apache Cassandra: its definition, architecture, components, data models, key features, advantages, and use cases in this comprehensive guide.
Cassandra uses a peer-to-peer architecture instead of the master/slave setup used in RDBMSs. There is no master server in the former like in peer-to-peer file sharing. If a master server stalls or breaks down because of numerous requests, the slave servers are rendered useless, whereas in...
Apache Cassandra 2.1 will have a safer, simpler, and often faster distributed counters implementation. The crucial difference is that rather than logging counter deltas (increments) directly to the commit log – making replay non-idempotent and potentially unsafe – Cassandra will now read the curren...
In the 2000s, innovations in web searching allowed for the development of MapReduce, Apache Hadoop, and Apache Cassandra to help discover, prepare, and present information. Future: Next-generation analytics As businesses shifted from just gaining data visibility and requiring more insight, the tools...
NoSQL stores (e.g., MongoDB, Elasticsearch, Cassandra). When to use different data storage options Most data lakes use a variety of storage options, depending on the data sources and business cases. This is especially true for business cases related to access and analytics. For example: ...

Examples of non-relational databases include MongoDB, Azure Cosmos DB, DocumentDB, Cassandra, Couchbase, HBase, Redis, and Neo4j. Some non-relational databases are referred to as NoSQL databases. NoSQL refers to data stores that use no SQL or not only SQL for queries. Instead, NoSQL databas...
