Properties

configDirectory

var configDirectory: String

The working directory whose wow/dataset/ holds dataset files, {context}.{dataset}.json; each takes precedence over the class path's META-INF/wow/dataset/ file of the same dataset.

maxConcurrent

var maxConcurrent: Int

How many dataset queries the node runs at once, so analytics queries do not overload a warehouse the Sink writes to; 0 for no bound. The bound is fixed: the warehouse's writes give the node no pressure to adapt to.

maxQueued

var maxQueued: Int?

How many dataset queries may wait for a permit before the next one is refused; wow.query.max-queued when not set.

maxWait

var maxWait: Duration?

How long a dataset query beyond max-concurrent waits for a permit; wow.query.max-wait when not set.
