Method Detail

configure

public void configure(Context context)

Description copied from interface: Configurable

Request the implementing class to (re)configure itself.

When configuration parameters are changed, they must be reflected by the component asap.

There are no thread safety guarrantees on when configure might be called.

Specified by:

configure in interface Configurable

process

public void process(Event event)

Description copied from interface: MorphlineHandler

Loads the given event into Solr

Specified by:

process in interface MorphlineHandler

beginTransaction

public void beginTransaction()

Description copied from interface: MorphlineHandler

Begins a transaction

Specified by:

beginTransaction in interface MorphlineHandler

commitTransaction

public void commitTransaction()

Description copied from interface: MorphlineHandler

Sends any outstanding documents to Solr and waits for a positive or negative ack (i.e. exception). Depending on the outcome the caller should then commit or rollback the current flume transaction correspondingly.

Specified by:

commitTransaction in interface MorphlineHandler

rollbackTransaction

public void rollbackTransaction()

Description copied from interface: MorphlineHandler

Performs a rollback of all non-committed documents pending.

Note that this is not a true rollback as in databases. Content you have previously added to Solr may have already been committed due to autoCommit, buffer full, other client performing a commit etc. So this is only a best-effort rollback.

Specified by:

rollbackTransaction in interface MorphlineHandler

stop

public void stop()

Description copied from interface: MorphlineHandler

Releases allocated resources

Specified by:

stop in interface MorphlineHandler
