Street-sensor analytics must run with limited memory while seeing only one pass or a sliding window of events. What trait should streaming algorithms accept?
Select an answer to reveal the explanation.
Short Explanation
Streaming math travels light: limited RAM, events that will not wait for a second full tour. One pass or a window is the deal, not “reload the whole lake first.” If the recipe needs the stream to end forever, it is not a streaming recipe.
Full Explanation
Streaming algorithms typically assume continuous input and bounded memory, operating in one pass or over windows rather than repeated full scans of all history. Unlimited multi-pass lake scans, mandatory forever materialization on one laptop, or waiting for a permanently closed stream violate those traits.
