[TRAFODION-2420] RMS enhancements Introduced 2 new counters HeapWM: - "SQL Heap WM" - Tracks the high water mark of the used memory including space buffer and bmo operator memory. It is enough to monitor this counter alone to track the memory utilization of the query.

scrIOTime: "Scr. IO Time" - Tracks the IO time taken to read/write to

the scratch files at BMO operator level

Introduced a 'Single line Format' option to display BMO stats and SE stats

in a single line format to enable exporting the output to Excel easily.


Removed and cleaned up the code further

Also fixed memory corruption issues seen with GET STATISTICS command.

[TRAFODION-2854] Improve SET STATISTICS command to display the information in new format

Currently SET STATISTICS ON | OFF alone is supported. It is improved to take some more options




This will display pertable, progress, operator level statistics for the these options respectively.

SET STATISTICS ALL will display both progress and operator level statistics.

These commands are valid both in sqlci and trafci.

jira TRAFODION-2234 turn aligned format on, phase 1

This is phase 1 of aligned format change.

Dev regressions now run with aligned format tables.

To test both hbase and aligned format, some tests have explicit

specification to create hbase format tables.

Tests that test for features that are currently only available

with hbase format (like pushdown sel expr) create hbase format tables.

Many expected files have been updated to reflect aligned format,

mostly in showddl and explain output.

[TRAFODION-1823] ESP idle timeout does not kick in, leading to too many ESPs on the system

Close message from the master was not sent to ESP by the platform

agnostic messaging layer in Trafodion. Fixed this bug and then ESP idle time

works as expected.

ESP_IDLE_TIMEOUT can now be given as a CQD. Internally, it would be

changed to SET SESSION DEFAULT and used by the IPC layer of Trafodion.

ESP_IDLE_TIMEOUT is set to 30 minutes by default in the CQD too.

Added test in core/TESTRTS to test ESP_IDLE_TIMEOUT

[TRAFODION-1771] Enabled TESTRTS again TESTRTS was failing at times with error 8926. This is due to absence of ROOT_OPER_STATS in statistics area, but the stats descriptor was incorrectly indicating that there is a ROOT_OPER_STATS.

In future, I will get rid of setting the accumulated statistics as part of

cleanup effort of the statistics collection.
