-----------------------------------
Summary: combine the Trx threads into one thread
Key: TRAFODION-3032
URL: https://issues.apache.org/jira/browse/TRAFODION-3032
Project: Apache Trafodion
Issue Type: Improvement
Components: dtm
Reporter: liu ming
Assignee: liu ming
At trx coprocessor start time, it will start two threads, one for lease, for
for old transaction cleanup. And there is a third memory monitor thread
currently not start by default.
These threads are per region.
In one system, there are 200 regions, so we saw RegionServer has over 680
threads, and it cause a high CPU usage, and high System Time usage.
One improvement is we can combine the threads into one, since they both are
periodic routines.
