Review comment:
This `documentType` variable is in the end used as a "table name". I find
the naming a bit confusing. Current situation makes me think it has to do
something with deprecated "mapping types".
I know there are no real "tables" in ES, but since this is already used e.
g. in "SimpleTableDef", I'd rather have it consistent.
I suggest to rename `documentType` on this line, and also the parameter name
of `detectTable` method, which, by the way, calls the document type an index
type.
Document type VS. index type VS. index name VS. table name VS. mapping type.
Perhaps I just lack ES terms being used here. :-) Then just ignore this
comment.
