Horizontal partitioning splits one or more tables by row, usually within a single instance of a schema and a database server. It may offer an advantage by reducing index size (and thus search effort) provided that there is some obvious, robust, implicit way to identify in which partition a particular row will be found, without first needing to search the index, e.g., the classic example of the ...
Some systems, like Cassandra, combine approaches using compound primary keys: hashing the first component for partitioning while maintaining sort order for remaining components within partitions [1]. In any partitioning scheme, data is typically arranged so that each piece of data (record, row, or document) belongs to exactly one partition [1 ...
These schemas are implemented for complex data warehouses. [1] The fact constellation is a measure of online analytical processing and can be seen as an extension of the star schema. A fact constellation schema has multiple fact tables. It is a widely used schema and more complex than star schemas and snowflake schemas.
