By the time we got out of this meeting developed late the actual planet day and yes it was almost time glimpse home. I let this whole event fester in my head for a bit and then started in order to it. Several individuals who employment in my department are either ready to retire (baby boomers) or simply below that age range.

With a sliding window, aggregating the streams of all sub-tables in the super table
CREATE STREAM current_stream
TRIGGER AT_ONCE
INTO current_stream_output_stb AS
SELECT
_wstart as start,
_wend as end,
max(current) as max_current
FROM meters
WHERE voltage <= 220
INTEVAL (5s) SLIDING (1s);
Let’s look at the second example, which in this case is a sliding window aggregation. After creating the stream, the trigger mode for the stream is specified via TRIGGER AT_ONCE. AT_ONCE mode means that when data is written, the computation is triggered immediately and the result is pushed without waiting for the window to close.
