WRITETIME question

Is there any reason to use the WRITETIME function on non-counter columns?

 

I'm using CQL statements via the thrift protocol and get a Timestamp
returned with each column.

 

I'm pretty sure select a, writetime(a) from b where u = 1 is unnecessary for
me. Unless a is a counter.

 

I guess my real question is.. What, if any, is the difference between
selecting writetime(column) and just looking at the Timestamp of a selected
column.

 

 

Thanks,

Chris

There's no difference. The writetime() function is only really necessary
for native protocol drivers, which don't normally get back the timestamp
for each column.
