I've been testing Cassandra - primarily looking at reads/second for our fairly data model - one unique key with a row of columns that we always request. I've now setup the cluster with with m1.large (2 cpus 8GB)
I had loaded a months worth of data in and was doing random requests as a torture test - and getting very nice results. I then loaded another days worth of day and repeated the tests while the load was running - still good. I then started loading more days and at some point the performance dropped by close to an order of magnitude ;-( Any ideas on what to look for ? thanks -- *Franc Carter* | Systems architect | Sirca Ltd <marc.zianideferra...@sirca.org.au> franc.car...@sirca.org.au | www.sirca.org.au Tel: +61 2 9236 9118 Level 9, 80 Clarence St, Sydney NSW 2000 PO Box H58, Australia Square, Sydney NSW 1215
