Secondary Index

What is a Secondary Index?

A Secondary Index is a secondary column by which you can sort data. CockroachDB supports both primary and secondary indexes. This just adds another level of organization to data sorting. For example, in a table of data about employees, you might first sort alphabetically by “name,” (the primary index) and then within that, sort alphabetically by “hometown” (the secondary index).
