On: Manticore 6.0.0 – a faster alternative to Elasticsearch in C++

[Shorel]

No, just because it's in C++ does not mean it is automatically faster.

However, with good enough algorithms and judicious coding and memory management, the possibility exists.

Also, architectural changes. They describe how ES can't parallelize a query unless it's spread across multiple index shards, which has its own tradeoffs. Their query engine can parallelize a query on a single index shard, which means it scales much more linearly on more cores without having to make those tradeoffs.

Which could also be done in Java.

Same can be said by Java, even without direct support for value types.

Plus it doesn't need to be Java xor C++, JNI exists for a reason (now Panama).
