METHODS AND SYSTEMS OF SPLITTING DATABASE INDEXES AND DIGESTS

摘要

A computer-implemented method of a distributed database system includes generating a database index. The method includes mapping a first specified number of bits of the database index to a database key. The method includes mapping a second specified number of bits to a data object associated with the database key. The method includes storing the first specified number of bits of the database key in a dram memory. The method includes storing second specified number of bits with the data object in a solid-state device (SSD) storage.

1. A computer-implemented method of a database comprising:
assigning a unique key to a record of a database; hashing the unique key into a digest; randomizing the digest; storing the digest in an index tree; assigning each index element to a node in the index tree; assigning twelve (12) bits of the digest to store information that determines which partitions to assign a record; assigning six (6) bits of the digest to store information that determines which storage device on which to store the record; assigning fourteen (14) bits to store information that determines a record lock to use on the record.
