Enrichment Tuning Example
We landed on the same number of partitions for enrichment and indexing as we did for bro - 48.
For configuring Storm, there is a flux file and properties file that we modified. Here are the settings we changed for Bro in Flux. +Note that the main Metron-specific option we've changed to accommodate the desired rate of data throughput is max cache size in the join bolts.
More information on Flux can be found here - https://storm.apache.org/releases/1.1.0/flux.html
