what is the meaning of optimize unix pipline and sql for time series data?
how this can happened?
Don't expect great syntax from a PowerPoint slide.
That item is trying to say SPL derives some of its syntax from Unix pipelines (that is, using the '|' character to funnel the output of one command into another) and from SQL (certain commands). The SPL language itself is focused on ("optimized") time-series data
Please explain your problem some more. In what context do you see that text?
