The most widely used data integration technique is extract, transform and load. ETL pulls data from source systems, converts it into a consistent format and then loads the integrated data into a data warehouse or other target system. However, data integration platforms now also support a variety...
While it does support other ACID-like features, such as strong consistency (using CL=ALL), compare-and-set updates with Lightweight Transactions, atomicity and isolation on the row-level, and has a durable writes option, it is inaccurate to describe Cassandra as an ACID-compliant database. ...
While Cassandra isn’t necessarily your traditional database, it is still ACID (Atomicity, Consistency, Isolation and Durability) compliant. One of the biggest feature sets of Apache Cassandra is its ability to create an environment without a single point of failure. This decentralized approach ...
The ACID test table will have two columns – A & B. There is an integrity constraint that the sum of values in A and B should always be 100. Atomicity testwill ensure any transaction performed on this table is all or none i.e. no records are updated if any step of the transaction ...
NewSQL is a new approach to relational databases that wants to combine transactionalACID(atomicity, consistency, isolation, durability) guarantees of good ol’ RDBMSs and the horizontal scalability of NoSQL. It sounds like a perfect solution, the best of both worlds. What took it so long to ...
