Make Your Queries 10x Faster with GBase 8a Rough Index

GBase 8a's Rough Index is a block-level indexing mechanism that stores min/max values per data block, enabling the optimizer to skip irrelevant blocks (block pruning) and reduce I/O by up to 90%. For maximum effectiveness, data should be loaded in sorted order by the frequently filtered column, range predicates should be preferred, and the index should be rebuilt after significant updates.
