While many efforts have been paid for query processing of data streams in distributed environment, no previous study focused on multiple-query optimization. To address this problem, we propose EsperDist, a distributed query engine for multiple-query optimization over data stream. EsperDist can ...

Updating statistical information and building covering indexes alone do not effectively reduce query time (as expected), so are there any other optimization methods? When the output row count is small, such as querying 0-100 rows or 0-1000 rows, the time difference between offset fetch ...
When you perform RetrieveMultiple queries on large datasets in Microsoft Dynamics CRM 2011, you experience slow performance. Cause This problem occurs because large datasets cache the Microsoft SQL query plans for the RetrieveMultiple queries. The RetrieveMultiple optimization for the basic depth is requ...

Multiple query optimization (MQO) in the cloud has become a promising research direction due to the popularity of cloud computing, which runs massive data analysis queries (jobs) routinely. These CPU/IO intensive analysis queries are complex and time-consuming but share common components. It is ch...
