configure

Method Detail

beginTransaction

void beginTransaction()

Begins a transaction

process

void process(Event event)

Loads the given event into Solr

commitTransaction

void commitTransaction()

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.

Throws:

IOException - If there is a low-level I/O error.

rollbackTransaction

void rollbackTransaction()

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.

Throws:

IOException - If there is a low-level I/O error.

stop

void stop()

Releases allocated resources
