We're playing around with Cassandra trying to get a feel for it. Can someone please explain the difference between load (from nodetool) and whats actually stored on disk? Sometimes these number mirror each other and sometimes the disk usage is up to 2x the load reported. as you can see below...
Cassandra 1 Keyspace Data Dir. Size (MB) System Data Dir Size (MB) Commit Log Data Dir Size (MB) Load (reported by ring) (MB) Initial 0 0.11 0.03 0.04 Run 1 254 0.11 344 253.23 Run 2 634 0.11 302 632.84 Run 3 1500 0.11 260 1012.46 Run 4 1400 0.11 219 1360 Run 5 2200 0.11 305 1610 Run 6 4000 0.11 264 1980 Run 7 2400 0.11 350 2350 Run 8 2800 0.11 309 2720 Run 9 3600 0.11 267 3090 Run 10 3400 0.11 354 3340 Run 11 3800 0.11 312 3710 Run 12 6100 0.11 271 4080 Run 3,5,6,9, and 12 don't seem to match up well. Can someone explain this please? Thank you.
