Ok, I updated the configs to expose all the settings that I could find for
committing and documented them. By default we operate safely, though. Though
now you can use soft commits rather than durable commits if you so desire and
wish to live dangerously.
> Update SolrWriter to conform to new collection strategy

> Key: METRON-1448
> URL: https://issues.apache.org/jira/browse/METRON-1448
> Project: Metron
> Issue Type: Improvement
> Reporter: Casey Stella
> Priority: Major
>
> Currently the SolrWriter presumes a single collection to be written to. The
> new collection strategy for Solr implies a collection per sensor. Also,
> there are a few rough edges in the writer which could stand smoothing:
> * By default, we use solr's implicit commit mechanism, rather than
> committing at the batch granularity. This may result in lost data on worker
> failure.
> * We do not use the the batch add api, but rather message-by-message add
