Abstract
A method for obtaining sample data includes associating data extracted from an incoming query with a key corresponding to an index table file, downloading data based on a filename, offset, and data range obtained from a table entry corresponding to the key, inserting the downloaded data to an inner join between a query table and a big data table, and obtaining data corresponding to a sample from the inner join.

A method for obtaining sample data, the method comprising:
- associating data extracted from an incoming query to a key corresponding to an index table file;
- downloading data based on a filename, offset, and data range obtained from a table entry corresponding to the key;
- inserting the downloaded data to an inner join between a query table and a big data table;
- and
- obtaining data corresponding to a sample from the inner join.
A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions readable/executable by a processor to cause the processor to:
- associate data extracted from an incoming query with a key corresponding to an index table file;
- download data based on a filename, offset, and data range obtained from a table entry corresponding to the key;
- insert the downloaded data to an inner join between a query table and a big data table;
- and
- obtain data corresponding to a sample from the inner join.
A computer system comprising:
- a processor;
- a memory accessible by the processor;
- and
- a computer readable medium having instructions encoded thereon to:
- associate data extracted from an incoming query with a key corresponding to an index table file;
- download data based on a filename, offset, and data range obtained from a table entry corresponding to the key;
- insert the downloaded data to an inner join between a query table and a big data table;
- and
