New features in Heritrix 3.0:
- Ability to run multiple crawl jobs simultaneously. The only limit on the number of crawl jobs that can run concurrently is the memory allocated to Heritrix.
- Single XML configuration file based on the Spring framework. This file replaces order.xml and other Heritrix 1.x configuration files.
- Ability to browse and modify the configured Spring beans through an easy-to-use browser based utility. See Bean Browser .
- Enhanced extensibility through the Spring framework. For example, domain overrides can be set at a very fine-grained level. See Sheets.
- More secure user control console. HTTPS is used to access and manipulate the user control console.
- Increased scalability. Previously, crawls with large seed values (tens or hundreds of millions) might attempt to utilize more memory than allocated to Heritrix. This would cause the crawl to crash. Heritrix 3.0 eliminates these problems, allowing stable processing of large scale scrawls.
- Increased flexibility when modifying a running crawl. Running crawls can be modified by using the Bean Browser or by using the Action Directory.
- Introduction of parallel queues. When crawling specific sites that can handle large amounts of traffic, the parallel queues option can be used to open many concurrent crawling connections to a single site.
- A Scripting Console that accepts script input in various formats such as AppleScript and ECMAScript. Scripting can be used to programmaticly access and manipulate the core components of Heritrix.
