Dublin buses, as is the norm with most road-based public transport systems in our increasingly car-choked cities, tend to operate on the basis of “no sign of a bus for ages, then two or three arrive at the same time”. Palo MOLAP ETL options appear to be following the same pattern; we’ve been waiting for ETL support for ages and now we see three of them heading down the road towards us. There’s Palo’s own offering, then came Stratebi‘s Kettle Plugin and now Talend Version 2.3.0RC2 is offering a Palo output component.
Mind you, the Talend offering is very basic and I’ve not managed to get the Sratebi plugin to work, leaving Palo’s ETL Server as the front runner at the moment (drill-through capability is a winner in my book).
I’ve also been busy re-factoring my VBA SQLite and Amazon S3 code with the intention of publishing them as an Excel based micro-ETL platform. While cleaning up the Amazon AWS modules I’ve been playing with SimpleDB, I’m impressed, Excel combined with SimpleDB rocks!
I’ve also wrapped the open source XySSL SHA1 HMAC C code in a VBA friendly DLL, as searching for a VBA hmac sha1 hash implementation (essential for Amazon AWS access) has proved fruitless.
Hope to release the lot the end of next month.
Thanks to Javier and Jorge from Stratebi I’ve managed to get the new Kettle Palo plugin to work. It seems that the TEST facility in the Kettle database connection dialogue throws an exception for Palo connections but the connections work fine in the actual Palo input/output steps. Did a quick test and it looks very easy to use and fits in well with the Kettle “way of doing things”.
