The parallelization decision for SQL queries has two components: the decision to parallelize and the degree of parallelism (DOP). These components are determined differently for queries, DDL operations, and DML operations. To determine the DOP, Oracle Database looks at the reference objects: ...

It provides an interface for programming all clusters with implicit data parallelism and fault tolerance. Talend Talend is an open-source data integration platform. It provides many services for enterprise application integration, data integration, data management, cloud storage, data quality, and Big ...
using them might lower efficiency. If you are seeing low parallelism due to a small volume of data (relatively few data blocks) in each table partition, increasing the row size by including complex columns might produce more data blocks and thus spread the work more evenly across the cluster....
MALT: Distributed Data-Parallelism for Existing ML Applications Machine learning methods, such as SVM and neural networks, often improve their accuracy by using models with more parameters trained on large numbers of examples. Building such models on a single machine is often impractical because of ...

a carry-select adder is a variant of the carry skip adder that further enhances the performance by using parallelism. it consists of multiple parallel adders with different carry-in values, allowing for simultaneous computation of multiple potential carry values. then, based on the carry-in value...

Concurrency:Since transactions are executed serially, there is no concurrency or parallelism in a serial schedule. Only one transaction is active at a time. Isolation:Serial schedules provide a high level of isolation between transactions. Each transaction has exclusive access to the database, and it...
