SET DATA STRUCTURE ▪️ A Python Set is the unordered and unique collection of the data. ▪️ Sets can contain elements of different Data Types Like int, string, Tuple, etc. but cannot contain List, sets, dictionaries. ▪️ Set data structure is used when you want… 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
Lists in Python ▪️ A list in Python is a group of related values (elements) that are arranged in a specific order and can be changed. ▪️ It can store different data types, including integers, floats, strings, and lists themselves. ▪️ Lists are enclosed in… Read More
Configure Agent (Linux-slave) machine with Jenkins Master using SSH key file connection – as Oracle OS user. ▪️ The Linux (slave) agent machine to be configured using SSH key file as Oracle OS user. ▪️ We have earlier successfully configured Agent using SSH key… 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
