Samarth Gahire commented on CASSANDRA-3589: ------------------------------------------- Actually i am just calculating the total time taken by the our program to generate the sstables.I can see this deference when i change the cassandra jar included in classpath of program. About CPU and IO utilisation i will check and let you know as soon as possible. > Degraded performance of sstable-generator api and sstable-loader utility in > cassandra 1.0.x > ------------------------------------------------------------------------------------------- > > Key: CASSANDRA-3589 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3589 > Project: Cassandra > Issue Type: Bug > Components: Tools > Affects Versions: 1.0.0 > Reporter: Samarth Gahire > Priority: Minor > > we are using Sstable-Generation API and Sstable-Loader utility.As soon as > newer version of cassandra releases I test them for sstable generation and > loading for time taken by both the processes.Till cassandra 0.8.7 there is no > significant change in time taken.But in all cassandra-1.0.x i have seen 3-4 > times degraded performance in generation and 2 times degraded performance in > loading.Because of this we are not upgrading the cassandra to latest version > as we are processing some TeraBytes of data everyday time taken is very > important. -- This message is automatically generated by JIRA.
