I tried to steer a “neutral” path on “start dates” - estimating “first customer use” rather than project availability and POC efforts. Clearly that data is not usually available, hence the variability on timing. Of course, may people have done CEP-based products (and re-usable “frameworks”) prior the availability of more general-purpose CEP products… probably we don’t want to document all those (in this chart anyway!). Then again, it might be interesting to have a version of this chart with “predecessor applications, specialist tools and projects”…

I agree with Jeff, very nice chart, thanks.

The Aleri Streaming Platform was actually released in Nov 2005, so it’s more in line with Coral8 timewise, in fact Coral8 announced months after Aleri (they were purposely under the radar for a period of time). Aleri also had a prior event processing framework on which we built Liquidity Management (a position management event streaming app), but given it was column-based it was not really low latency, that work goes back to 1999.

You might also want to Google the Sunrise Project, which one of my teams productized under the name QTM while at Bell Labs Research and later Lucent’s Software Business Unit. We called it real-time event analytics/processing back then and we were unable to spin it out as a venture given the market was not yet ready for this sort of framework, so instead we built and sold apps using it under the Kenan brand. This was another relational-based event processing framework utilizing SQL for modeling.

Hope this helps.
Best,
Jerry
