indexes

Whether an index catalog is created, collected into and read from.

false costs nothing, in the same sense as schema: no .idx base sidecar is written for a segment, so a store that will never be indexed carries no index overhead at all.

With this off, Rabosh.query, Rabosh.createIndex and the rest of the query surface throw: the planner is built around an index catalog, and a query with no catalog is Rabosh.scan under a different name rather than a degraded plan.
