Database System Concepts 7th Edition ©Silberschatz Korth and Sudarshan Parallel Query Processing Different queries/transactions can be run in parallel with each other • Interquery parallelism • Concurrency control takes care of conflicts in case of updates • More on parallel transaction processing in Chapter 23 • Focus in this chapter is on
6 Optimizer Query Parser & Translator Relational Algebra Optimizer It will select the query which has low cost Example 1 ΠENAME σDUR>37∧= EMP × ASG 2 ΠENAME EMP ENO σDUR>37 ASG Optimizer will select Expression2 as it avoids the expensive and large
2 ·Fast Vector Query Processing for Large Datasets Beyond GPU Memory with Reordered Pipelining Authors Zili Zhang Fangyue Liu Gang Huang Xuanzhe Liu and Xin Jin School of Computer Science Peking University Abstract Vector query processing powers a wide range of AI applications While GPUs are optimized for massive vector operations
Query optimization in relational database management systems DBMSs is critical for fast query processing The query optimizer relies on precise selectivity and cost estimates to effectively optimize queries prior to execution While this strategy is effective for relational DBMSs it is not sufficient for DBMSs tailored for processing machine learning ML

Query processing is the most complicated subsystem in PostgreSQL and it efficiently processes the supported SQL This chapter outlines this query processing in particular it focuses on query optimization This chapter comprises the following three parts Part 1 Section This section provides an overview of query processing in PostgreSQL
Local differential privacy LDP has been established as a strong privacy standard for collecting sensitive information from users Although it has attracted much research attention in recent years the majority of existing works focus on applying LDP to frequency distribution estimation for each individual value in a discrete domain This paper concerns the important range queries
Distribution Query Execution • The last layer is performed by all the sites having fragments involved in the query • Each sub query executing at one site called a local query is then optimized using the local schema of the site and executed Query processing problem Syntax Errors One of the first problems in query processing is parsing the user s
The problem of query processing can itself be decomposed into several subproblems corresponding to various layers A generic layering scheme for query processing is shown where each layer solves a well defined subproblem To simplify the discussion let us assume a static and semicentralized query processor that does not exploit replicated
Analyzing and mining of time series have been widely studied in both academia and industry in recent years Given a set of long time series data analysts can utilize the window based similarity search to explore subsequences in arbitrary time windows Existing techniques are not efficient for window based query processing In particular the whole matching index approach needs to

Main Problems of Query Processing Main problem of query processing is query optimization It is a time consuming task because many execution strategies are involved to minimize optimize computer resource consumption Time and space required to process the query is also an important factor for the performance of the query processing 6
