[jira] [Created] (HBASE-9780) Total row num to write in
PerformanceEvaluation vary on thread number
Liu Shaohui created HBASE-9780:
----------------------------------
Summary: Total row num to write in PerformanceEvaluation vary on thread number
Key: HBASE-9780
URL: https://issues.apache.org/jira/browse/HBASE-9780
Project: HBase
Issue Type: Improvement
Reporter: Liu Shaohui
Priority: Minor
Total row num to write in PerformanceEvaluation vary on thread number
{code}
// Set total number of rows to write.
this.R = this.R * N;
{code}
Different row num may result in different random read perf. More threads, More rows, may less block cache hit raito.
Should we make the total row num be immutable for different thread numer?
