Replaces Parquet output and processing with the new Slop-based format. Includes data migration functionality, updates to handling and writing of crawl data, and introduces support for SLOP in domain readers and converters.
Adding a tracking message to the export actor means it's possible to run them in a precession.
Adding a new precession actor, and some GUI components for triggering exports.
The change also adds a heartbeat to the export process.
This is to prevent data corruption. This shouldn't be necessary for the regular loader path, but the live crawler is a bit different and needs some paving of the road ahead of it.
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.
Move the logic deciding which operation to perform into the actor, updating its state graph to incorporate a counter that runs a clean update once in a blue moon.
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.
Add a new actor that polls an URL every 6 hours and amends the domain database with any unseen domains, flagging them to be crawled by the next crawl job.
The URLs are specified in data/scrape-urls.txt. If this file is absent, the actor shuts down.
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.
Don't wait until the loader step is finished to reset the NEW flag, as this leaves manually processed (but not yet loaded) crawl data stuck in "CREATING" in the GUI.
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.
The change adds a new system property 'system.profile' that makes ProcessService automatically trigger JFR profiling of the processes it spawns. By default, these are put in the log directory.
The change also adds a JVM parameter that makes it shut up about native access.
Roll back to JDK 21 for now, and make Java version configurable in the root build.gradle
The project has run into no less than three distinct show-stopping bugs in JDK22, across multiple vendors, and gradle still doesn't fully support it, meaning you need multiple JDK versions installed.
