This plugin does not bundle any JDBC jar files, and does expect them to be in a
particular location. Please ensure you read the 4 installation lines below.
## Headlines
- Support for connection pooling added in 0.2.0
- Support for unsafe statement handling (allowing dynamic queries) in 0.2.0
- Altered exception handling to now count sequential flushes with exceptions thrown in 0.2.0
## ChangeLog
See CHANGELOG.md
## Versions
Released versions are are tagged as of v0.2.1, and available via rubygems.
For development:
- See master branch for logstash v2+
- See master branch for logstash v2
- See v1.5 branch for logstash v1.5
- See v1.4 branch for logstash 1.4

## Running tests
Assuming valid JDBC jar, and jruby is setup and installed, and you have issued `jruby -S bundle install` in the development directory
- `SQL_JAR=path/to/your.jar jruby -S bundle exec rspec`
If you need to provide username and password you may do this via the environment variables `SQL_USERNAME` and `SQL_PASSWORD`.
At this time tests only run against Derby, in an in-memory database.
Acceptance tests for individual database engines will be added over time.
Tests are not yet 100% complete.
Assuming valid jruby is installed
- First time, issue `jruby -S bundle install` to install dependencies
- Next, download Derby jar from https://db.apache.org/derby/
- Run the tests `JDBC_DERBY_JAR=path/to/derby.jar jruby -S rspec`
- Optionally add the `JDBC_DEBUG=1` env variable to add logging to stdout
