New Stuff

Oracle or MySQL for configuration database Berkeley DB for data store

Embedded database Reasonable open-source license

Import legacy data Data compression (6 TB / year .8 TB / year)

84% lossless 92%, truncating timestamps to milliseconds

Improved command-line tools Expiration dates for logging requests

Scalability

Data store decoupled from data acquisition multiple engines can spool data

Embedded database indexes, summarizes data fast lookup easily shuffle data offline/online fast retrieval

History server reduce data before transporting
