New Parameter for Journal cleanup

clebert.suconic Jul 1, 2009 9:08 PM

I need to add two parameters to the configuration:

compactPercenptual - the % on which we start compacting.

minCompactSize - In number of journal files. (We only start considering compacting after a certain number of data files).

Example: compactPercenptual = 30, minCompactSize=10

We will start compacting when more than 70% of the data on the journal is considered dead space and we have at least 10 files as data files on the journal.

The minCompactSize definition is important, or else we would start compacting too soon. We don't want to start compact when we have only one file on the journal for example.

Any suggestions for better names are appreciated.

thanks...

Just thought of a better name:

- compactPercenptual
- journalCompactMinFiles

but I'm still opened for suggestions.

I have actually written percentual when I wrote on the code. (pfew!... I thought I used the wrong word there also)


public class Configuration
....

 int getJournalCompactMinFiles();

 void setJournalCompactMinFiles(int minFiles);

 int getJournalCompactPercentage();

 void setJournalCompactPercentage(int percentage);

...

 journalCompactMinFiles = getInteger(e, "journal-compact-min-files", journalCompactMinFiles, GE_ZERO);

 journalCompactPercentage = getInteger(e, "journal-compact-percentage", journalCompactPercentage, PERCENTAGE);
