Field Summary

Fields

Modifier and Type	Field and Description
static int	DEFAULT_MAX_RECLEN
static boolean	DEFAULT_RAW_RECORDS
static int	DEFAULT_WRITE_RETENTION_QUEUE_CAPACITY
static String	MAX_RECLEN When RAW_RECORDS are used, this will be the maximum byte length of a byte[] value before it is written as a raw record on the backing store rather than inlined within the bucket page (default 128 .
static String	RAW_RECORDS When true raw record references will be written on the backing store and the index will manage the mapping between the keys and the storage addresses rather than having the byte[] values inline in the bucket page (default DEFAULT_RAW_RECORDS).
static String	WRITE_RETENTION_QUEUE_CAPACITY
