Additionally, the diverging mathematical foundations of data processing and machine learning hinder cross-optimizations by combining these two components, thereby overlooking potential opportunities to expedite predictive pipelines. In this paper, we propose an operator fusion method based on GPU-accelerated ...
In recent years, there has been tremendous interest in research that applies machine learning to database systems. Being one of the most complex components of a DBMS, query optimizers could benefit from adaptive policies that are learned systematically from the data and the quer...
ReSQLThe ReSQL database system was developed as a showcase for low-latency query compilation with Flounder IR.Footnote1ReSQL provides a full translation stack from SQL to machine code and supports a variety of queries. We discuss the interaction of ReSQL’s translation components with Flounder ...
Most of the CQL language is operational in the STREAM system. We present the structure of CQL's query execution plans as well as details of the most impor- tant components: operators, interoperator queues, synopses, and sharing of components among multiple operators and queries. Examples through...

This does not distinguish between tasks of operating systems and DBMSs. In this paper, we claim that building from scratch a green query processors and revisiting existing ones pass through 4-steps procedure: (1) establishment of a deep audit that allows understanding the query processor ...
The package DBMS_ODCI contains a function estimate_cpu_units to help get the CPU and I/O cost from input consisting of the elapsed time of a user function. estimate_cpu_units measures CPU units by multiplying the elapsed time by the processor speed of the machine and returns the approximate...
4. Consider the consequences if the query processor also had to handle modifiers such as “in the book with the unicorn logo on each page,”“in the draft on Alan’s hard drive,” or “after the reference to a popular mountain resort.” ...
components, data structures and the like that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the invention may be practiced with other computer system configurations, including hand-held devices, multi-processor systems, micr...
A DBMS may define an external table in response to receiving a DDL (Data Definition Language) statement that describes the external table. The DDL statement specifies one or more columns for the external table (“DBMS table columns”) and an external data source of the external table, such as...
