hi, I want to fetch all the row keys of a table using CQL3: e.g select id from mytable limit 9999999
#1 For this query, does the node need to wait for all rows return from all other nodes before returning the data to the client(I am using astyanax) ? In other words, will this operation create a lot of load to the initial node receiving the request? #2 if my table is big, I have to make sure the limit is set to a big enough number, such that I can get all the result. Seems like I have to do a count(*) to be sure.... is there any alternative(always return all the rows)? #3 if my id is a timeuuid, is it better to combine the result from couple of the following cql to obtain all keys? e.g select id from mytable where id t < minTimeuuid('2013-02-02 10:00+0000') limit 20000 + select id from mytable where id t > maxTimeuuid('2013-02-02 10:00+0000') limit 20000 thanks
