Subject [jira] [Commented] (CONNECTORS-55) Bundle database server with LCF packaged product
Date Sat, 02 Apr 2011 12:24:05 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-55?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13015021#comment-13015021

Karl Wright commented on CONNECTORS-55:
---------------------------------------

The current status of this feature request is as follows:

- There is a Quick Start, which can run either with Derby or with PostgreSQL, depending on
what you put in connectors.xml.
- We've done a lot of fixes to the Derby support, although there are two outstanding tickets
that need to be resolved before it can be considered "real".  See CONNECTORS-100 and CONNECTORS-110.
- You can run the Quick Start with embedded Derby in a mode that allows external connections.
"java -Dderby.drda.startNetworkServer=true -jar start.jar".  If you want a truly multiprocess
ManifoldCF running, you will also need to set up file-based synchronization, as described
in how-to-build-and-deploy.html.
- Instructions for how to run Quick Start with PostgreSQL are in the FAQ.
- I coded an HSQLDB implementation, but that's stalled because HSQLDB internally deadlocks.
 See CONNECTORS-114.
- Nobody has looked at H2 in any depth yet.  Not clear if we still need to.

> The current requirement that the user install and deploy a PostgreSQL server complicates
the installation and deployment of LCF for the user. Installation and deployment of LCF should
be as simple as Solr itself. QuickStart is great for the low-end and basic evaluation, but
a comparable level of simplified installation and deployment is still needed for full-blown,
high-end environments that need the full performance of a ProstgreSQL-class database server.
So, PostgreSQL should be bundled with the packaged release of LCF so that installation and
deployment of LCF will automatically install and deploy a subset of the full PostgreSQL distribution
that is sufficient for the needs of LCF. Starting LCF, with or without the LCF UI, should
automatically start the database server. Shutting down LCF should also shutdown the database
server process.
> A typical use case would be for a non-developer who is comfortable with Solr and simply
wants to crawl documents from, for example, a SharePoint repository and feed them into Solr.
QuickStart should work well for the low end or in the early stages of evaluation, but the
user would prefer to evaluate "the real thing" with something resembling a production crawl
of thousands of documents. Such a user might not be a hard-core developer or be comfortable
fiddling with a lot of software components simply to do one conceptually simple operation.
> It should still be possible for the user to supply database server settings to override
the defaults, but the LCF package should have all of the best-practice settings deemed appropriate
for use with LCF.
> One downside is that installation and deployment will be platform-specific since there
are multiple processes and PostgreSQL itself requires a platform-specific installation.
> This proposal presumes that PostgreSQL is the best option for the foreseeable future,
but nothing here is intended to preclude support for other database servers in futures releases.
> This proposal should not have any impact on QuickStart packaging or deployment.
> Note: This issue is part of Phase 1 of the CONNECTORS-50 umbrella issue.
