multi-db-set-bits sets bits with increasing profile id and bitmap id using a different DB for each agent.
Agent num changes the database being written to.
Usage: multi-db-set-bits [arguments]
The following arguments are available:
-base-bitmap-id int
bits being set will all be greater than base-bitmap-id
-base-profile-id int
profile id num to start from
-iterations int
number of bits to set
-client-type string
Can be 'single' (all agents hitting one host) or 'round_robin'
-content-type string
protobuf or pql
