Complex event processing (CEP)
Discussion of complex event processing (CEP), aka event processing or stream processing – i.e., of technology that executes queries before data is ever stored on disk. Related subjects include:
My skeptical remarks on the Aleri/Coral8 merger generated some pushback. Today I actually got around to talking with John Morell, who was marketing chief at Coral8 and has remained with the combined company. First, some quick metrics:
- The combined Aleri has around 100 employees, 60-40 from Aleri vs. Coral8.
- The combined Aleri has around 80 customers. All of Aleri’s, with one sort-of exception at Banks.com, were in financial services. A large minority of Coral8’s were in financial services too.
- However, half of Aleri’s marketing spend going forward is budgeted outside the financial services markets. Not unreasonably, John presents this as a proof point Aleri is serious about selling to other markets.
- Aleri had 12-14 people in the UK pre-merger. Coral8 had none in Europe.
- Coral8 had 15 OEMs pre-merger, some actually generating revenue. Aleri had substantially none.
- Coral8 had been closing a “couple” of customers/quarter in online commerce. But recently, that rate ramped up to a “few.”
- Aleri’s engine is used to handle “many” hundreds of thousands of messages per second. Coral8’s highest-throughput user processes 100-150,000 messages/second.
John is sticking by the company line that there will be an integrated Aleri/Coral8 engine in around 12 months, with all the performance optimization of Aleri and flexibility of Coral8, that compiles and runs code from any of the development tools either Aleri or Coral8 now has. While this is a lot faster than, say, the Informix/Illustra or Oracle/IRI Express integrations, John insists that integrating CEP engines is a lot easier. We’ll see.
I focused most of the conversation on Aleri’s forthcoming efforts outside the financial services market. John sees these as being focused around Coral8’s old “Continuous (Business) Intelligence” message, enhanced by Aleri’s Live OLAP. Aleri Live OLAP is an in-memory OLAP engine, real-time/event-driven, fed by CEP. Queries can be submitted via ODBO/MDX today. XMLA is coming. John reports that quite a few Coral8 customers are interested in Live OLAP, and positions the capability as one Coral8 would have had to develop had the company remained independent. Read more

I’m not aware of anyone claiming “CEP is an alternative to a relational RDBMS” – except maybe as an application platform for processing events (where RDBMS could be seen as a square hole for an event round peg).
Actually, it’s hard to think of an application for off-the-shelf CEP where the alternative technologies aren’t:
- Custom CEP
- Just write it to an RDBMS and query it
Independent CEP (Complex/Event Processing) vendors continue to flounder, at least outside the financial services and national intelligence markets.
- StreamBase once planned to conquer the world, making an impact as big as database management’s. Now it has retreated into niche markets.
- Progress Software, a decent-sized company, put a large fraction of its energy into Apama. Little has happened outside the financial service sector.
- Coral8 has some great-sounding ideas. But Coral8 now has merged into Aleri, basically a financial-markets specialist.
- Mike Franklin says some ambitious things on behalf of Truviso, but I haven’t noticed much traction there either.
CEP’s penetration outside of its classical markets isn’t quite zero. Customers include several transportation companies (various vendors), Sallie Mae (Coral8), a game vendor or two (StreamBase, if I recall correctly), Verizon (Aleri, I think), and more. But I just wrote that list from memory — based mainly on not-so-recent deals — and a quick tour of the vendors’ web sites hasn’t turned up much I overlooked. (Truviso does have a recent deal with Technorati, but that’s not exactly a blue chip customer these days.)
So far as I can tell, this is a new version of a repeated story. Read more

When I went to Oracle in October, the main purpose of the visit was to discuss Exadata. And so my initial post based on the visit was focused accordingly. But there were a number of other interesting points I’ve never gotten around to writing up. Let me now remedy that, at least in part. Read more

It used to be that Coral8 and StreamBase were the two complex event/stream processing (CEP) vendors most committed to branching out beyond the super-low-latency algorithmic trading marketing. But StreamBase seems to have pulled in its horns after a management change, focusing much more on the financial market (and perhaps the defense/intelligence market as well). Aleri, Truviso, and Progress Apama, while each showing signs of branching out, don’t seem to have gone as far as Coral8 yet. And so, though it’s a small company with not all that many dozens of customers, my client Coral8 seems to be the one to look at when seeing whether CEP really is relevant to a broad range of mainstream – no pun intended – applications.
Coral8 today unveiled a new product release – the not-so-concisely named “Coral8 Engine and Portal Release 5.5” – and a new buzzphrase — “Continuous Intelligence.” The interesting part boils down to this:
Coral8 is proposing CEP — excuse me, “Continuous Intelligence” — as a data-store-equivalent for business intelligence.
This includes both operational BI (the current sweet spot) and dashboards (the part with cool, real-time-visualization demos). Read more

It should surprise nobody that web analytics – and specifically clickstream data — is one of the biggest areas for high-end data warehousing. For example:
- I believe that both of the previously mentioned petabyte+ databases on Greenplum will feature clickstream data.
- Aster Data’s largest disclosed database, by almost two orders of magnitude, is at MySpace.
- Clickstream analytics is a big application area for Vertica Systems.
- Clickstream analytics is a big application area for Netezza.
- Infobright’s customer success stories appear to be concentrated in clickstream analytics.
- Coral8 tells me that CEP is also being used for clickstream data, although I suspect that a lot of Coral8’s evidence in that regard comes from a single flagship account. Edit: Actually, Coral8 has a bunch of clickstream customers.

Doug Henschen has two good articles based on Gartner’s Event Processing conference, on the theme of BI/event processing integration — an overview, and a detailed interview with Roy Schulte. And as I note elsewhere, Seth Grimes has a good article based on the conference too.
I have my own thoughts on these subjects, but I’m not ready to post them at the moment. In the mean time, I recommend the articles linked above.

Marco Seiriö offers a distinction between event processing and data-driven processing. Specifically, he says that if an event has an ID, then it’s true event processing; if it doesn’t, and what you’re doing looks somewhat like event processing anyway, then you’re doing data-driven processing.

Truviso and EnterpriseDB announced today that there’s a Truviso “blade” for Postgres Plus. By email, EnterpriseDB Bob Zurek endorsed my tentative summary of what this means technically, namely:
There’s data being managed transactionally by EnterpriseDB.
Truviso’s DML has all along included ways to talk to a persistent Postgres data store.
If, in addition, one wants to do stream processing things on the same data, that’s now possible, using Truviso’s usual DML.
I talked with both Coral8 and Truviso this afternoon. They both have their financial services efforts, of course. Coral8 also continues to get business doing data reduction for sensor networks — mainly RFID and utilities, I think. Coral8 is working on some really cool and confidential other stuff as well.
But my biggest takeaway from this pair of calls was that Coral8 and Truviso are penetrating general BI. Read more
