Subject:Quick question on row counts
View as plain text  
Hello everyone,

I have a quick question. Testing seems to indicate that Falcon keeps 
accurate stats on the number of rows in a table. It appears similar to 
the way MyISAM tables work.  This can shown by running a 'SHOW TABLE 
STATUS' command and comparing the number of rows with the SELECT 
COUNT(*) command. Am I correct in this? Or have I not done enough tests?

Also, SELECT COUNT(*) appears to return a number of rows much quick than 
a similar command on InnoDB tables. Again..similar to MyISAM. Am I 
accurate in this?

thanks,

Keith
