> I've been working on a generic JDBC sink. It needs a bit more testing, but I
> think it's ready for review and feedback. I have not yet updated the Flume
> documentation, but I can / will if people are happy with this.
> Since the config file is how you’d interact with it, here’s a working example
> from my source tree:
> {code}
> a.sinks.k.type=jdbc
> a.sinks.k.channel=c
> a.sinks.k.driver=com.mysql.jdbc.Driver
> a.sinks.k.url=jdbc:mysql://localhost:8889/flume
> a.sinks.k.user=username
> a.sinks.k.password=password
> a.sinks.k.batchSize=100
> a.sinks.k.sql=insert into twitter (body, timestamp) values (${body:string},
> ${header.timestamp:long})
> {code}
> The interesting part is the SQL statement. You can put anything you want in
> there - it will get converted to a prepared statement on execution. The
> Ant-ish tokens get parsed and replaced with parameters at startup.
> The tokens are three part. For example, in:
> {code}
> ${body:string(UTF-8)}
> {code}
> The first is a place in the event to get the value from (“body”,
> “header.foo”, or “custom”). The second part ("string") is a type identifier
> that converts into an appropriate JDBC parameter. The third part (“UTF-8")
> is a configuration string for that type, if needed. As for types, so far
> I’ve defined:
> body: string (with optional charset encoding), bytearray
> header: string, long, int, float, double, date (with mandatory date format
> and optional timezone)
> Additionally, if none of those make you happy you can define you own
> parameter converters:
> {code}
> ${custom:com.company.foo.MyConverter(optionaltextconfig)}
> {code}
