Abstract
The present disclosure involves systems, software, and computer implemented methods for generating a hash identifier. One example method includes: identifying a record to include in a table, the record associated with two or more primary key fields that are concatenated to create a concatenated key, wherein the table includes one or more hash columns for storing hash identifiers; applying a hash function to the concatenated key to create a new hash value; determining whether a record in the table has a hash value matching the new hash value; in response to determining that a hash value of a record matches the new hash value and the concatenated key of the identified record does not match the concatenated key of any existing record, adding a counter to the new hash value to generate a unique hash ID; and storing the record, including the unique hash ID, in the table.
