More from Vertica on data warehouse load speeds
Last month, when Vertica releases its “benchmark” of data warehouse load speeds, I didn’t realize it had previously released some actual customer-experience load rates as well. In a July, 2008 white paper that seems thankfully free of any registration requirements, Vertica cited four examples:
- (Comcast) Trickle loads 48MB/minute – SNMP data generated by devices in the Comcast cable network is trickle loaded on a 24×7 basis at rates as high as 135,000 rows/second. The system runs on 5 HP ProLiant DL 380 servers.
- (Verizon) Bulk loads to memory 300MB/minute – 50MB to 300MB of call detail records (1K record size—150 columns per row) are loaded every 10 minutes. Vertica runs on 6 HP ProLiant DL380 servers.
- (Level 3 Communications) Bulk loads to disk 5GB/minute – The loading and enrichment (i.e., summary table creation) of 1.5TB of call detail records formerly took 5 days in a row-oriented data warehouse database. Vertica required 5 hours to load the same data.
- (“Global investment firm”) Trickle loads 2.6GB/minute – Historic financial trade and quote (TaQ) data was bulk loaded into the database at a rate of 125GB/hour. New TaQ data was trickled into the database at rates as high as 90,000 rows per second (480b per row).

ParAccel’s market momentum
After my recent blog post, ParAccel is once again angry that I haven’t given it proper credit for it accomplishments. So let me try to redress the failing.
- ParAccel has disclosed the names of two customers, LatiNode and Merkle (presumably as an add-on to Merkle’s Netezza environment). And ParAccel has named two others under NDA. Four disclosed or semi-disclosed customers is actually more than DATAllegro has/had, although I presume DATAllegro’s three known customers are larger, especially in terms of database size.
- ParAccel sports a long list of partners, and has put out quite a few press releases in connection with these partnerships. While I’ve never succeeded in finding a company that took its ParAccel partnership especially seriously, I’ve only asked three or four of them, which is a small fraction of the total number of partners ParAccel has announced, so in no way can I rule out that somebody, somewhere, is actively helping ParAccel try to sell its products.
- ParAccel repeatedly says it has beaten Vertica in numerous proofs-of-concept (POCs), considerably more than the two cases in which it claims to have actually won a deal against Vertica competition.
- ParAccel has elicited favorable commentary from such astute observers as Seth Grimes and Doug Henschen.
- ParAccel has been noted for running TPC-H benchmarks in memory much more quickly than other vendors run them on disk.
Uh, that’s about all I can think of. What else am I forgetting? Surely that can’t be ParAccel’s entire litany of market success!
