The new table names will make it easier to tell table properties from table names in post-mortem analysis. - table size increases with the table name's position in the alphabet - tables with same letters (e.g. 'A' and 'AA') are of the same size, but using different engines. - all single-letter tables are MyISAM tables, all double letter tables are InnoDB (with current data generator). This change also eliminates table names that were not in use (32 tables are generated).	John H. Embretsen	14 years ago

0.67.674	Various optional extensions to ExecutionTimeComparator. Various optional extensions to ExecutionTimeComparator. Whether to use these can be configured by editing variables or constants in the top of the file (ExecutionTimeComparator.pm). If needed one can make it configurable via the command line later. - Skip EXPLAIN comparison. In some cases EXPLAIN output comparison is not interesting and/or too expensive. Set the variable $skip_explain to 1 to skip this. Default is 0 (EXPLAIN comparison enabled). - Query repetition: Repeat each query N times (default 0) and calculate and use the average execution times for these repetitions instead of numbers from single runs. Single executions may too often yield false positives due to for example background activity. - File output: Notable results written to tab-separated text file. Queries with ratios outside the given thresholds will be written to the text file along with the ratio, reversed ratio, time0 and time1. This will then be easy to import into a spreadsheet or other tools for further processing. Default behavior is to write to a file ("rqg_executiontimecomp.txt"). To disable this, undef the variable $outfile. - Table variation: For simple queries selecting from a single table, it is possible to repeat the query against other tables specified in the @tables array. This is useful for (e.g.) comparing ratios for tables of different sizes. The @tables array is by default empty, in which case no such extra executions will take place.	John H. Embretsen	14 years ago
