Hi, I was reading http://wiki.apache.org/cassandra/FAQ#iter_world and decided to implement the get_range_slices method for listing all keys of a CF. Only thing is, it doesn't work that well for me :-)
I do as it says (I think), and take KeyRanges of size N and use the key of the last call as start for next call. But, for small N, I keep getting the exact same result back from get_range_slices call, making it impossible to know when to stop. For N=5, the first slice of keys I get back is this: previousLastKey = keySlice.getKey() = xaspays keySlice.getKey() = xasfbbe keySlice.getKey() = xaspaua keySlice.getKey() = xasaapz keySlice.getKey() = xascajz I then call with previousLastKey = xascajz and get: previousLastKey = xascajz keySlice.getKey() = xascajz keySlice.getKey() = xasgacr keySlice.getKey() = xasfaem keySlice.getKey() = xasfdco keySlice.getKey() = xasfdeg I then call with previousLastKey = xasfdeg and get: previousLastKey = xasfdeg keySlice.getKey() = xasfdeg keySlice.getKey() = xasfdad keySlice.getKey() = xascaiv keySlice.getKey() = xasfaqf keySlice.getKey() = xasfdeg <--- ENDS IN THE SAME KEY AS PREVIOUS SLICE ? ... the above 5 keys keep getting back as the exact same result :-( If I set N higher, like 100, I get all my (2492) rows... /Per
