[jira] [Updated] (CASSANDRA-11542) Create a benchmark to compare HDFS and Cassandra bulk read times

     [ https://issues.apache.org/jira/browse/CASSANDRA-11542?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stefania updated CASSANDRA-11542:
---------------------------------
    Description: 
I propose creating a benchmark for comparing Cassandra and HDFS bulk reading performance. Data will be imported into Spark to perform very simple queries and the entire duration will be measured. An example query would be the max or min of a column or a count\(*\).

This benchmark should allow determining the impact of:
* partition size
* number of clustering columns
* number of value columns (cells)
