Cluster Vertica : How does the distributed Query behave when all tables are unsegmented ?

Hello,

How the distributed query works on a cluster of Vertica when all my (small) tables are stored in mode replication (unsegmented) ?

For example, when i submit a SELECT FROM <table>, I think that only one node available on the cluster execute the SELECT.

 

Someone can confirm it ?

 

Many thanks for your help

  • Yes.  If a projection is "UNSEGMENTED" (i.e., replicated) then whatever node you run the query on will answer the query exclusively. It won't involve any other node in the query execution.
