BaseArrayIndex
abstract public class BaseArrayIndex extends BaseIndex implements Index(Code)
Abstract base implemenation for Index indices that maintain an in-memory, sorted array of key values (and their associated row identifiers). This type of index is fast to read, relatively slow to write and somewhat memory expensive when very large.
