You could use the official SolrBolt from Lucidworks (https://github.com/LucidWorks/storm-solr) and put your messages into Solr using batch sizes of 1000 or even 10000. As Andrew pointed out, the second option is to write your messages to HDFS and afterwards use the Job Jar to load the data into Solr. The command looks something like this: hadoop jar /opt/lucidworks-hdpsearch/job/lucidworks-hadoop-job-2.0.3.jar com.lucidworks.hadoop.ingest.IngestJob -Dlww.commit.on.close=true -cls com.lucidworks.hadoop.ingest.DirectoryIngestMapper --collection my_collection -i /data/* -of com.lucidworks.hadoop.io.LWMapRedOutputFormat --solrServer http://c6601.ambari.apache.org:8983/solr ...

There is some interesting information in this mail thread https://news.ycombinator.com/item?id=9463809 "I'm one of committers of Apache Zeppelin (incubating). Zeppelin is inspired by iPython notebook and many other amazing softwares that has notebook interface. I know iPython notebook has long history and large community, i really like it. Zeppelin is young, new project compare to iPython notebook. Zeppelin and iPython notebook, they are opensource. iPython notebook is lead by IPython Development Team. Zeppelin is under Apache Software Foundation and it is being developed in Apache way, from copyrights, development process, decision making process to community development. Zeppelin is focusing on providing analytical environment on top of Hadoop eco-system. I'm not sure about iPython's direction, but i don't think it's the same to Zeppelin. I see many projects that has notebook interface. Not only iPython and Zeppelin, but also Databricks Cloud, Spark Notebook, Beaker and many others. I'm sure they all have their own advantages. Hope see all softwares are beloved by users." ... View more
