New and updated features.

Query Language Enhancements

  • New function globalFilter(). This function is similar to retainSeries(), but filters are pushed all the way into the inner ts()/hs() expressions. That means you can use globalFilter() to filter data pre-aggregation.
  • New function join() that is modeled after the SQL JOIN operation. Use the function to see relationships among your time series to build full stack correlations.
  • Function atEpoch() is now documented.

Tracing Improvements

This release supports several tracing improvements.
