Verify doc key generation.
Add some simple tests to verify behavior of doc key gen.
Fix warmup.
Warmup behavior was in the wrong place, hence causing reuse of keys.
Option WarmupMs
Decrease. Couchbase is so fast.
DocKeyGenerator
It should generate per workload. Each workload can not have dep to other workloads and their keys.
Workload index
Since each workload can be executed many times if you have concurrent clients, a workload index has been introduced so that unique keys can be generated.
