The goal is to end mistaken choices among join algorithms by replacing the three traditional join algorithms with a single one, which can replace both merge filexlib. GRAEFE et al.: SORT VS. HASH REVISITED. 937. For sorting, it is well known that merging is limited to the quotient of memory size and buffer space required Sorting is a fundamental operation for database query processing. Therefore, we explored techniques to speed up external merge sort.

Database cracking and adaptive merging are two techniques for adaptive indexing. Graefe, G., Idreos, S., Kuno, H., Manegold, S.: Benchmarking adaptive In a pure OLTP workload that requires only record-to-record navigation, intuition agrees that index nested loops join is sufficient. For a DSS workload,
