Wasn't it the other way around? Wasn't Storm killed by Spark? At least once Spark was out and gained traction, nobody in my bubble talked about Storm anymore. But I guess it depends on the bubble you're in.

Wouldn't Flink be more likely to replace Spark? I don't hear about a lot of people using Storm these days, but I guess a lot of this depends on whatever bubble you happen to be in.

in what world was spark killed by storm/heron? last i checked the spark conference had over 10k attendees this year. storm is barely supported and heron never picked up steam.

What ?

Spark Streaming is just one part of Spark and the far less used part as well.

Spark hasn't been killed by anything and is still heavily used for ETL and ML.

No one uses Storm anymore. It was Spark that killed Storm, not the other way around.
