Also alter CrawledDocument to not require String parsing of the underlying byte[] data. This should reduce the number of large memory allocations quite significantly, hopefully reducing the GC churn a bit.
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.
Previously, the sideloader did not generate a locality-sensitive hashCode for document details. This caused all documents from the same domain to be considered duplicates by the deduplication logic.
If the document's URL path is "/", a "special:root" meta flag is now added with the "Synthetic" bit set. This will help searching only for the root document of a website, neat stuff ahead :D
Centralized HTML feature handling with `applyFeatures` in StackexchangeSideloader and added dynamic synthetic term generation. Improved HTML structure in RedditSideloader and enhanced metadata processing with feature-based keywords. Updated DomainLinks to correctly compute link counts using individual link occurrences.
Normalize URLs by replacing en-dash with hyphen to prevent encoding errors. This ensures correct handling of a small subset of articles with improperly normalized UTF-8 paths. Added `normalizeUtf8` method to address this issue.
Fixes issue #109.
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.
This is done by applying a large constant offset to the ordinals for the live crawled documents. The chosen value still permits upto 100k documents to be fetched for a single domain with the live crawler, which is ridiculously large.
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 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 help offer verbatim matches for external link texts, we assign these positions in the document a bit after the actual document ends. Integrating this information with the ranking is not performed here.
