BRIN stands for Block Range Index. BRIN indexes are different from indexes such as B-tree indexes. BRIN indexes do not store index details based on row IDs, but store the statistics of each data block or a series of consecutive data blocks. Therefore, BRIN indexes occupy a small amount of memory and have small impacts on data writes, updates, and deletion.
