INTERVIEW QUESTIONS DATA WAREHOUSING DATASTAGE DETAILS

Question: What does separation option in static hash-file mean?

Answer: The different hashing algorithms are designed to distribute records evenly among the groups of the file based on charecters and their position in the record ids.

When a hashed file is created, Separation and Modulo respectively specifies the group buffer size and the number of buffers allocated for a file. When a Static Hashfile is created, DATASTAGE creates a file that contains the number of groups specified by modulo.

Size of Hashfile = modulus(no. groups) * Separations (buffer size)
