//------------------------------------------------------------------------------
|
|
// This method is intended to test the messages used to profile db performance.
|
|
// The method also provides an example on how to use these log messages.
|
|
// Test can be verified by viewing /var/log/mariadb/columnstore/debug.log.
|
|
//
|
|
// Message types are:
|
|
//
|
|
// 26 Start Transaction
|
|
// 27 End Transaction
|
|
// 28 Start Statement
|
|
// 29 End Statement
|
|
// 30 Start Step
|
|
// 31 End Step
|
|
// 32 I/O Reads
|
|
//
|
|
// The messages should be logged in the following way:
|
|
//
|
|
// 1. The application should log a StartTransaction message at the beginning
|
|
// of a database transaction.
|
|
// 2. When the application begins processing a statement, the StartStatement
|
|
// message should be logged.
|
|
// 3. As each primitive step is executed, it's start time should be recorded
|
|
// by logging a StartStep message.
|
|
// 4. During the execution of a step, 1 or more I/O Read messages should be
|
|
// logged to record the I/O block count used in accessing each object. If
|
|
// necessary, more than 1 message can be logged for the same object and
|
|
// step. In these cases, the script that post-processes the syslog will
|
|
// add up the block counts for the same object and step.
|
|
// 5. Upon completion of each primitive step, an EndStep message should be
|
|
// logged. If multiple steps are executing in parallel, the EndStep msg
|
|
// should be logged as each step completes. After all these stpes are
|
|
// completed and logged, if needed, a new set of StartStep messages can
|
|
// be logged (for the same statement), for a new set of parallel steps.
|
|
// 6. Upon completion of each statement, an EndStatement msg should be logged.
|
|
// 7. Upon completion of each transaction, an EndTransaction msg should
|
|
// be logged.
|
|
//
|
|
// Some possible enhancements to simplify this profile logging for the
|
|
// application programmer:
|
|
//
|
|
// 1. Define enum or const ints in a common header file to represent the
|
|
// list of valid subSystem ids.
|
|
//
|
|
// 2. Add set of helper methods to MessageLog class to reduce the
|
|
// amount of work for the application. For example a method like:
|
|
//
|
|
// void logStartStatement ( int statement, int ver, string SQL );
|
|
//
|
|
// would allow the application to log a StartStatement by simply doing;
|
|
//
|
|
// Message msgStartStatement ( M0028 );
|
|
// int statementId = 11;
|
|
// int versionId = 22;
|
|
// string sql ("SELECT column1, column2 FROM table1 WHERE ...
|
|
// msgStartStatement.logStartStatement ( statementId, versionId, sql);
|
|
//
|
|
// 3. Could also do something similar to #2 except instead of adding helper
|
|
// methods to MessageLog, we could add specialized classes that derive
|
|
// from MessageLog or contain a MessageLog. One advantage of doing it
|
|
// this way is that a derived class like MessageLogStatement "could" be
|
|
// implemented to log the StartStatement, and its desctructor could then
|
|
// log the EndStatement automatically, on behalf of the application.
|
|
