Apache Camel is an open source framework for message-oriented middleware with a rule-based routing and mediation engine that provides a Java object-based implementation of the Enterprise Integration Patterns using an application programming interface (or declarative Java domain-specific language) to configure routing and mediation rules.
CXF is often used with Apache ServiceMix, Apache Camel and Apache ActiveMQ in service-oriented architecture (SOA) infrastructure projects. Apache CXF supports the Java programming interfaces JAX-WS, [ 2 ] : 638 JAX-RS, JBI, JCA, JMX, JMS over SOAP, Spring , [ 2 ] : 635–641 and the XML data binding frameworks JAXB, Aegis, Apache XMLBeans, SDO.
Apache Parquet is implemented using the record-shredding and assembly algorithm, [7] which accommodates the complex data structures that can be used to store data. [8] The values in each column are stored in contiguous memory locations, providing the following benefits: [9] Column-wise compression is efficient in storage space
A keyspace example with a number of column families. A keyspace (or key space) in a NoSQL data store is an object that holds together all column families of a design. [1] [2] It is the outermost grouping of the data in the data store. [3] It resembles the schema concept in Relational database management systems. [4]
Data orientation is the representation of tabular data in a linear memory model such as in-disk or in-memory. The two most common representations are column-oriented (columnar format) and row-oriented (row format). [1] [2] The choice of data orientation is a trade-off and an architectural decision in databases, query engines, and numerical ...

This function requires a small value delta. A good choice for delta is the cube root of the machine epsilon. [citation needed]. The type of the function d indicates that it maps a float onto another function with the type (float-> float)-> float-> float. This allows us to partially apply arguments. This functional style is known as currying.
YAML (/ ˈ j æ m əl /, rhymes with camel [4]) was first proposed by Clark Evans in 2001, [15] who designed it together with Ingy döt Net [16] and Oren Ben-Kiki. [16]Originally YAML was said to mean Yet Another Markup Language, [17] because it was released in an era that saw a proliferation of markup languages for presentation and connectivity (HTML, XML, SGML, etc.).
