What problem does this PR solve?
Improve the coverage of batch-write on unique indices.
What is changed and how it works?
In this PR, we are trying to improve the coverage of batch-write on unique indices.
In order to test the correctness of batch-write, we have to create different schemas with different numbers of the index on the schema. Additionally, we have to prepare data and use batch-write api to perform the insertion.
After discussion with @birdstorm, we decided we should generate the schema, so does the data.
To generate different schemas, we create an array of
dataTypes. Our schema generator enumerates over thedataTypesand chooses some of them to become unique indices.Once we have schema, we generate data randomly.
With schema and data, it is ready to test our batch-write api.
