Hello Rob,
    
    I now see I had misspelled the word tall for toll, anyways, if I    
understood correctly, your reply implies there is no impact    whatsoever and 
there is no need to defrug indexes of the frequently    changing columns. 

Am I right?
 
Thank you!

 

Regards,

Arthur

In Cassandra to just be able to query (in CQL) on a column I have to have an 
index, the question is what tall the fragmentation coming from the frequent 
updates and inserts has on a CF? Do I also need to manually defrug? 




You have appeared to have just asked if maintaing indexes which have a high 
rate of change in a log structured database with immutable data files is likely 
to be more performant than maintaining them in a database with modify-in-place 
semantics.


"No."
