Joey Frazee commented on SPARK-8696:
------------------------------------
Is there still interest in this? The two use cases I've seen for this are (1)
low latency, or near real-time topic generation -- imagine a dashboard or
process depending on _always_ up-to-date topic dist. -- and (2) desire to do
updates rather than fitting the entire dataset again because it's very large or
very expensive to pre-process – though maybe merely having topic-word priors
such as suggested in SPARK-9134 could be a good enough alternative for this
second use case. I've seen both of those requirements appear in tandem.
