Vector databases extend the capabilities of traditional relational databases to embeddings. However, the key distinguishing feature of a vector database is that query results aren’t an exact match to the query. Instead, using a specified similarity metric, the vector database returns embeddings that...
甚至可以基于 vector 的内存无复制创建新的 Buffer。ClickHouse 内部的关于压缩文件的读写,远程文件(S3、HTTP)的读写都是基于 BufferBase 的衍生类。 为了在 ClickHouse 层面零复制拿到 SQL 运行的结果,我使用了内置的 WriteBufferFromVector 来替换 stdout 接收数据。这样既能保证并行输出的 Pipeline 不会阻塞又能保...

GIS users work with different vector-based spatial data formats, like published layers on remote servers (web layers) and local data. The Spatially enabled DataFrame allows the users to read, write, and manipulate spatial data by bringing the data in-memory. The SeDF integrates with Esri's Ar...
If your task requires facial recognition on large datasets, you should combine DeepFace with a vector index or vector database. This setup will performapproximate nearest neighborsearches instead of exact ones, allowing you to identify a face in a database containing billions of entries within milli...
