hadoop - Hive file formats advantages and disadvantages -


I start working with the hive. I wanted to know which questions should be used for each table format in formats: rcfile, orcfile, wooden roof, delimited text

When you have a large number of columns and you frequently use specific columns, then RC file format will be a good option instead you will retrieve the required columns instead of reading the entire line of data, Save time in this way . The data is divided into groups of rows, which are later divided into groups of columns.

The delimited text file is the normal file format.
