[jira] [Created] (HDDS-14473) Freon should not use secure random for data generation

Andrey Yarovoy created HDDS-14473:
-------------------------------------

             Summary: Freon should not use secure random for data generation
                 Key: HDDS-14473
                 URL: https://issues.apache.org/jira/browse/HDDS-14473
             Project: Apache Ozone
          Issue Type: Bug
            Reporter: Andrey Yarovoy


Freon should not use secure random for generating data for writing. The most efficient way of generating random data from multiple threads is ThreadLocalRandom.nextBytes().

 

Assuming that non of Ozone's components use compression or deduplication we can use repeating sequence of hash(filename) for writing data, it would allow us to validate data for reads.
