Summary: Implement persistent storage for Nutch Webserver resources
Key: NUTCH-2926
URL: https://issues.apache.org/jira/browse/NUTCH-2926
Project: Nutch
Issue Type: Improvement
Components: nutch server, storage
Reporter: Lewis John McGibbney
Assignee: Lewis John McGibbney
The Nutch webserver caches resources (seed lists, configuration, jobs, etc.)
in-memory. This is not a reliable or resilient solution for the longer term use
of Nutch server in the enterprise.
I propose to add a persistence layer which will address this problem.
I intend to use JOOQ as a thin layer on top of JDBC. This will provide
flexibility for deploying a wide variety of RDBMS backends.
h2 is a popular, very lightweight (~2.5 MB) appropriately-licensed solution we
could use as the initial backend. I intend to use it in embedded mode with
enabled persistence so we'll have data on the disk. This means that if we stop
Nutch server we can restart and restore server resources from disk.
