org.apache.cassandra.thrift.SliceRange
A slice range is a structure that stores basic range, ordering and limit information for a query that will return multiple columns. It could be thought of as Cassandra's version of LIMIT and ORDER BY @param start. The column name to start the slice with. This attribute is not required, though there is no default value,and can be safely set to '', i.e., an empty byte array, to start with the first column name. Otherwise, it must a valid value under the rules of the Comparator defined for the given ColumnFamily. @param finish. The column name to stop the slice at. This attribute is not required, though there is no default value,and can be safely set to an empty byte array to not stop until 'count' results are seen. Otherwise, it must also be a valid value to the ColumnFamily Comparator. @param reversed. Whether the results should be ordered in reversed order. Similar to ORDER BY blah DESC in SQL. @param count. How many columns to return. Similar to LIMIT in SQL. May be arbitrarily large, but Thrift willmaterialize the whole result into memory before returning it to the client, so be aware that you may be better served by iterating through slices by passing the last value of one call in as the 'start' of the next instead of increasing 'count' arbitrarily large.
