I’m increasingly pessimistic on ES as a solution. Everyone is coming to eat their lunch. APM? Datadog. Product search? Algolia.
I think the next wave of search tech will be
1. Leveraging automated ingestion optimization.
2. Capable of searching across mixed media: text, audio, images to start out with. This is only possible because of optimized ingestion. The ingestion layer will perform vectorization of the inputs. The vectors will be the entires stored in inverted indices.
3. A great jump from two to an optimized data store for searching mixed media.
People obsessing over elastic/splunk features are lost. Nobody will care in 5 years. Both will be legacy enterprise tech.
