Subject About data file size and on-disk size
Date Tue, 22 Nov 2016 15:19:35 GMT
Hi,
 


 
I have a table with 16 buckets over 3 physical machines. The tablet only has one replica.
 


 
Tablets Web UI shows that each tablet has around ~4.5G on-disk size.
 
In one machine, there are total  8 tablets, so the on-disk size is about 4.5*8 = 36G.
 
however, in the same machine, the disk actually used is about 211G.
 


 
# du -sh /data/kudu/tserver/data/
 
210G /data/kudu/tserver/data/
 


 
# find /data/kudu/tserver/data/ -name "*.data" | wc -l
 
8133
 


 


 
What’s the difference between data file and on-disk size. 
 
Can files in  /data/kudu/tserver/data/ be compacted, purged, or some of them be deleted?
 


 
Thanks very much.
