My naive reading of CASSANDRA-1417 was that it could be used to save the row cache to disk. Empirically it appears to only save the row keys, and then reads each row. In my case I set the row cache to save to disk. This resulted in a 25 MB file. On restart the process sat at this line for about 1 hour while reading at 25 MB a second: INFO [main] 2011-01-11 07:32:41,705 ColumnFamilyStore.java (line 252) loading row cache for FOO of BAR Is this the intentional implementation? Are there any reason not to just the entire row to disk to allow for faster startup?
