There is a relatively limited set of benchmarks over strings, dates, etc. A typical string length is 16 or 30, there is one test with 5M chars.

Implement in Genny:

• A benchmark with collection with large strings  (100 - 1000 chars)
• Add more collections with dates and timestamps.
• Fields of mixed data types
• Add queries exercising type bracketing and plan cache:
• The same query shape with constants of different types that would generate different plans.
