    Lightning-Fast Retrieval with Robust Support

    Reviewed on Nov 05, 2025
    Review provided by G2
    What do you like best about the product?
    I truly love using Zilliz for building our video retrieval tool as it has greatly enhanced our ability to convert each frame of a video into vectors and store them effectively in Zilliz Cloud. This functionality allows for accurate and efficient searches for corresponding images or videos, whether making searches from text to images or vice versa. The support from Zilliz is impeccable, with a very active community and extremely reliable database systems, which gives us a great deal of confidence. The most impressive aspect is the retrieval speed; it is exceptionally fast, allowing us to search through millions of vectors in just 200 milliseconds, which is critical for our operations. Additionally, the ability of Zilliz to handle a large capacity of data further boosts its value, making our data management and retrieval processes smooth and efficient.
    What do you dislike about the product?
    I think the number of vector columns supported in a single collection is a bit low, it seems to be 4 or 8. We would like to be able to search across more dimensions.
    What problems is the product solving and how is that benefiting you?
    I use Zilliz to convert video frames into vectors stored in Zilliz Cloud, facilitating accurate image or video retrieval. The retrieval speed is extremely fast, processing millions of vectors in 200 milliseconds, and the capacity is very large.
