There are some cases, such as tests or gitbase regression tests where you don't want to create the indexes in the background because you need them to be created before you start doing queries.

Do this manually requires a lot of knowledge about the insides and they are susceptible to change. By optionally letting the user decide if they should be sync or async we can abstract all this away and just use a query to create them.

It could be some config or environment variable.

WDYT? @ajnavarro
