I am not sure what do you mean with distribuition but the table projection_storage can tell you how many rows an used bytes you have per node per projection. Maybe this is what you are looking for ?
Thanks for replying. My question is like i want to know the work load distribution across the nodes when i pass some select query. If i am passing 'select xyz from abc where some_condition' , i want know, in each node how the load distributed among
if you add the keyword PROFILE before the statement vertica will save the profile information in the execution_engine_profiles table. In that table you could look in each part of the query per node how many bytes were read, how many rows where produced, etc. The table keeps a lot of info so you will need to do some aggregation queries to look at it.
