>>>>> The query is asking for 5000 different partitions to be selected across
the cluster. This is a very EXPENSIVE query for Cassandra, especially as the number of nodes
goes up. Typically, you want to query a single partition. Read timeouts are usually caused
by queries that are selecting many partitions or a very large partition. That is why a schema
for the involved table could help.
