Hello,
for a scientific test application, we have been using MySQL. So far, our database has grown above 4TB and we expect it to grow around 30Gbite per day for some more time (years).
We use innodb, which is split so far over 4 1Tb files. OS is Windows Server 64bit, Mysql 5.1 x64
There are two issues concerning us:
-The database has grown too far to switch to a file per table setup as it would simply take too long to convert. But also the 'max' setting in defining the innodb file size is only applicable to the last file and therefore we have to create the next ibdatafile manually each time we reach a certain threshold. We do not want the individual files grow too large as it is already hard enough to handle. Is there a better way to split the files? I do not want to end up with a 10TB innodb file in one piece....
-Secondly, are there any experiences with innodb as large as 10-30TB? We feel a bit more uncomfortable every day... ;)
Still we can not really change the current set up...
Do you have suggestions on this? Any opinion and help is appreciated!
Thanks and cheers, Sam
