ClickHouse® is a fast, open-source column-oriented database management system that can generate analytical data reports through SQL queries in real time. According to several independent benchmarks, it far exceeds other comparable column-oriented database management systems, working even up to 1000 times faster. It is able to process hundreds of millions to more than a billion rows and tens of gigabytes of data per single server per second. Apart from its blazing speed, ClickHouse is highly...

...LevelDB supports arbitrary byte arrays as both keys and values, singular get, put and delete operations, batched put and delete, bi-directional iterators and simple compression using the very fast Snappy algorithm. LevelDB stores entries sorted lexicographically by keys. This makes the streaming interface of levelup - which exposes LevelDB iterators as Readable Streams, a very powerful query mechanism. The most common store is leveldown which provides a pure C++ binding to LevelDB. Many alternative stores are available such as level.js in the browser or memdown for an in-memory store. ...

...I have stepped on many pitfalls, after several version iterations, as well as the feedback and help of many netizens, and model testing. The picture is distorted, some devices do not automatically rotate the direction of the picture, and there is no jpeg compression algorithm. New Blob is not supported, and the size of the file constructed by formData is 0. There are also inexplicable bugs in some models and browsers (such as QQX5 browser).
