- Warehouse
- Maria suggests two undergraduate students put up an OLAP application on top of Joao's Data Warehouse.
- Maria already has a an ETL (Extraction Transforming Loading) process for a small Data Warehouse they had at UFRJ (done Cristiane). This could be adapted to maintain the SLAC Data Warehoues from the FTP hourly PingER data.
- One of Maria's students (Rafaelo) has a cluster of four Impala/Hadoop nodes. He can use SPARQL to make analytical queries (not sure if data is PingER or other)
- Renan interested in speeding up queries from the Warehouse
- Semantic web
- Bebo, Renan
- Visualization & analysis
- Marcos, Claudio and Antonio
- One thing they are looking at is real-time visualization, which neds fast response. From Renan's work a couple of years ago response time to OLAP queries of 100 million tuples was ~ 30 seconds.
- Marcos, Claudio and Antonio
