supportsRangeOptimization#

Get Signature#

get supportsRangeOptimization(): boolean;

Defined in: packages/db/src/indexes/base-index.ts:101

Whether range lookups (gt/gte/lt/lte) on this index can be trusted to return every matching key. Range traversal relies on the index ordering, so it is unsafe when the index uses a custom comparator, whose order may not match the WHERE evaluator's relational operators. Callers must fall back to a full scan when this is false.

Returns#

boolean

valueMapData#

Get Signature#

get valueMapData(): Map<any, Set<TKey>>;

Defined in: packages/db/src/indexes/base-index.ts:90

Returns#

Map<any, Set<TKey>>
