Question

What is streaming access?

Answer 1

Data is not read as chunks or packets but rather comes in at a constant bit rate. The application starts reading data from the beginning of the file and continues in a sequential manner.

Answer 2

As HDFS works on the principle of ‘Write Once, Read Many‘, the feature of streaming access is extremely important in HDFS. HDFS focuses not so much on storing the data but how to retrieve it at the fastest possible speed, especially while analyzing logs. In HDFS, reading the complete data is more important than the time taken to fetch a single record from the data.
