Table RequestStats is quite big in my old site (campsite 3.3.3) and I would like to know if is it safe do deleta all data which is older than 2014-01-01 to speed up backup proces.
Size of table RequestStats on disc:
# du -sh RequestStats* 12K RequestStats.frm 506M RequestStats.MYD 1.8G RequestStats.MYI
No of all records:
mysql> select count(*) from RequestStats; +----------+ | count(*) | +----------+ | 33093293 | +----------+ 1 row in set (0.00 sec)
No of all year 2014 records:
mysql> select count(*) from RequestStats where date >= "2014-01-01"; +----------+ | count(*) | +----------+ | 1376478 | +----------+ 1 row in set (24.96 sec)
