IndexType enum
IndexType can be used to change what type ObjectBox uses when indexing a property.
Limits of hash/hash64 indexes: Hashes work great for equality checks, but not for "starts with" conditions. If you frequently use those, consider value indexes instead for String properties.
Values
- value → const IndexType
-
Uses property values to build the index. This is a default for scalar properties.
If used for a String property, this may require more storage space than it's default, hash.
- hash → const IndexType
-
Uses a 32-bit hash of the field value; default for String properties.
Hash collisions should be sporadic and shouldn't impact performance in practice. Because it requires less storage space, it's usually a better choice than hash64.
- hash64 → const IndexType
-
Uses a long hash of the field value to build the index. Uses more storage space than hash, thus should be used with consideration.
