Strings are indexed - on disk using our proprietary on-disk byte-ordered trie data structure, while numeric types are indexed using a - balanced tree. + on disk using a byte-ordered trie data structure, while numeric types are indexed using a block-oriented balanced tree. - While indexes continue to be managed at the column level from the user's perspective, the storage design at the column index level is row-based, with related offset and token information stored only once at the SSTable level. This drastically reduces our on-disk footprint when several columns are indexed on the same table. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
