چکیده

In operation research, there is no single method available for solving all optimization problems. Hence a number of techniques have been developed for solving different types of optimization problems. Optimization is the act of obtaining the best result under given circumstances. The ultimate goal of optimization is either to minimize the efforts required or to maximize the desired benefit [5]. Query Optimization is one of the optimization problems in database management system. It is a process of determining the most efficient way to execute a given query by considering the possible query plans. The approach suggested in the paper is mainly focused on join operation of the query. Previous work done was based on semi-join approach for query optimization but a semi-join needs more local processing such as projection and higher data transmission. To improve the previous approach, the filter based approach is utilized. The evaluation of filter is done by considering the collisions occurred, using perfect hash function and using sets of filters. Paper focuses on importance of optimization and Intelligent Bloom Join filter approach for data reduction in query optimization. Keywords—Optimization; Query Optimization; Bloom Join; Bloom Filter.

Complex Query JOIN Optimization in Parallel Distributed Environment

The research work covers the query optimization concept in parallel distributed environment. The queries considered are select-project-join (SPJ) queries with large databases. The main query operation considered for research is JOIN operation of the query. For fast execution of a complex query, JOIN operation time needs to be minimized. Different JOIN operation algorithms such as Network Byte O...

Bloom Filters in Distributed Query Execution

The MapReduce framework [5] has emerged as a successful parallel computation model in large-scale data analytics, mostly due to its simple interface and its scalability over thousands of nodes. However, while various primitives, such as aggregations, are performed efficiently in this framework, more complicated relational algebra operations such as joins and multiway joins are still implemented...

Memory-Efficient Hash Joins

We present new hash tables for joins, and a hash join based on them, that consumes far less memory and is usually faster than recently published in-memory joins. Our hash join is not restricted to outer tables that fit wholly in memory. Key to this hash join is a new concise hash table (CHT), a linear probing hash table that has 100% fill factor, and uses a sparse bitmap with embedded populatio...

In-Network Processing of an Iceberg Join Query in Wireless Sensor Networks Based on 2-Way Fragment Semijoins

We investigate the in-network processing of an iceberg join query in wireless sensor networks (WSNs). An iceberg join is a special type of join where only those joined tuples whose cardinality exceeds a certain threshold (called iceberg threshold) are qualified for the result. Processing such a join involves the value matching for the join predicate as well as the checking of the cardinality co...

Fast and deterministic hash table lookup using discriminative bloom filters

Hash tables are widely used in network applications, as they can achieve O(1) query, insert, and delete operations at moderate loads. However, at high loads, collisions are prevalent in the table, which increases the access time and induces non-deterministic performance. Slow rates and non-determinism can considerably hurt the performance and scalability of hash tables in the multi-threaded par...
