The code was always blocking for up to 5s while waiting for the remote end to become available, meaning some services would stall for several seconds on start-up for no sensible reason.
This should make most services start faster as a result.
Also correct the DbDomainQueries.getDomainId so that it throws NoSuchElementException when domain id is missing, and not UncheckedExecutionException via Cache.
This update eliminates all occurrences of the OpenNLP token model from the setup script, configuration, and test files, as this model file is no longer used.
Introduced optional alias domain functionality in EdgeDomain class to handle domain variations such as "www" in the anchor tags code, as there are commonly a number of relevant but glancing misses in the atags data.
Since some of the export tasks have been memory hungry, sometimes killing the executor-services, they've been moved to a separate process that can be given a larger Xmx.
While doing this, the ProcessMainClass was given utilities for the boilerplate surrounding receiving mq requests and responding to them, some effort was also put toward making the process boot process a bit more uniform. It's still a bit heterogeneous between different processes, but a bit less so for now.
Node profiles decide which actors are started, and which views are available in the control GUI. This helps keep the system organized, and hides real-time clutter from the batch-oriented nodes.
Some refactoring is still needed, but an dummy actor is in place and a process that crawls URLs from the livecapture service's RSS endpoints; that makes it all the way to being indexable.
The new service 'status-service' will poll public endpoints periodically, and publish a basic read-only UI with the results, as well as publish the results to prometheus.
We can only do this for files that are not required for unit tests.
As it is illegal to run more than one instance of the control service, this should be fine with regard to race conditions. The boot orchestration will also ensure that no other services will boot up before the downloading is complete.
The crawl spec abstraction was used to upload lists of domains into the system for future crawling. This was fairly clunky, and it was difficult to understand what was going to be crawled.
Since a while back, a new domains listing view has been added to the control view that allows direct access to the domains table. This is much preferred and means the operator can directly manage domains without specs.
This commit removes the crawl spec abstraction from the code, and changes the GUI to direct to the domains list instead.
To be able to tell service discovery whether to enable a service on a particular runtime, a common base interface DiscoverableService extends BindableService was added.
Refactoring keyword extraction to extract spans information.
Modifying the intermediate storage of converted data to use the new slop library, which is allows for easier storage of ad-hoc binary data like spans and positions.
This is a bit of a katamari damacy commit that ended up dragging along a bunch of other fairly tangentially related changes that are hard to break out into separate commits after the fact. Will push as-is to get back to being able to do more isolated work.
