> Queries that don't use an index are potentially very slow, even if the result is small (and even if there is no result).
> There should be a (configurable) query timeout. The default could be one minute. A bit tricky is to distinguish between an application that is reading the results slowly and the query performing slowly: we can't simply measure the start time of the query and throw an exception when reading and the timeout has been reached; instead, either the total execution time needs to be calculated, or the timeout should only apply for reading one entry.
> An open question is how to configure the timeout.
