DATATYPES IN CQL (2.0) CUSTOM DATA TYPE: A Custom datatype is defined by every Java class that extends the server-side Abstract Type class and can be loaded by Cassandra is called a custom type; as a result, it should be included in the CLASSPATH of every… Read More
DATA TYPES IN CQL The Cassandra Query Language, or CQL, is supported by Apache Cassandra. Cassandra Apache The categories of data known as data types specify the kinds of data that can be kept in a variable or object. Programmers instruct the compiler on how… Read More
CASSANDRA QUERY LANGUAGE WHAT IS CASSANDRA QUERY LANGUAGE? The computer languages used to create queries in databases and information systems are known as query languages. The main query language used to interact with the Apache Cassandra database is called Cassandra Query Language. A model resembling… Read More
GUI TOOLS FOR APACHE CASSANDRA An interface containing visual elements like buttons or icons that the user uses to interact with electronic equipment is known as a graphical user interface (GUI) tool for Apache Cassandra. The enhancement of graphical user interface’s usability for the typical… Read More
CASSANDRA DATA MODELING TOOLS You can create queries and maintain your Cassandra schema with a number of available tools. KASHLEV DATA MODELER: The data modeling process outlined in this paper, which includes defining access patterns, conceptual, logical, and physical data modeling, and schema development, is automated… Read More
DEFINING THE SCHEMA Dividing the large partitions: The objective is to create tables that, in the event that a single partition is touched by a query, can yield the necessary data. Nonetheless, it is feasible to create broad partition-style tables that go close to Cassandra’s inherent… Read More
EVALUATING AND REFINING DATA MODELS /*After you’ve produced a physical model, you’ll want to assess and tweak table designs to assist ensure optimal performance.*/ PARTITION SIZE CALCULATON: The first thing you should look for is if your tables will have too large partitions, or, to… Read More
PHYSICAL DATA MODELING IN CASSANDRA Creating the physical model is a reasonably simple task once the logical data model has been developed. You go through each of the logical model tables, giving each object a type. Any valid CQL data type, including the basic kinds,… Read More
LOGICAL DATA MODELING To start with Cassandra data modeling, we are ready to begin designing Cassandra tables. From the conceptual model we must create a logical model containing a table for each query, capturing entities and relationships. Then identify the primary entity type for which… Read More
RULES FOR DATA MODELLING IN CASSANDRA: Cassandra is a query language which is resembles with SQL, but the modulation of data is completely different when compared with other data types. In Cassandra, a worst model of data can lower the performance, especially when the data… Read More
