[continuations]

I remember reading about this a few years ago here. If I remember correctly back then the main selling point was that it used succinct data structure and it was only the compression algo that was not open source - everything else was.

But now when I look at the new repo and the online doc there is no mention of succinct data struct anywhere.

Also, the benchmarks back then claimed 10x or more faster than RocksDB. Now the performance claim is much more modest.

Does that mean TerarkDB no longer uses succinct data struct? Or are you just open sourcing a lower-end version of the software without the secret sauce?

Can you talk about what makes TerarkDB faster than RocksDB?

Thanks for your attention, glad someone here still remember our history, TerarkDB is now FULLY open source with `succinct data structures`.

Here's the reasons: 1. Our `all-in-one` docs are still under writing, we will cover that part later. 2. For the performance part, we are now showing real-world cases, not a well-designed benchmark.(We selected the best result to show our work few years ago, don't want to do it anymore) 3. About why TerarkDB is faster than RocksDB will be explained in our `all-in-one docs` in one week, and most of the reasons are not magic, just engineering efforts

Thanks again for your remembering us.

So... You're saying there is magic? :)

Great. Looking forward to learn more about this.
