VasSonic is a lightweight and high-performance Hybrid framework developed by tencent VAS team, which is intended to speed up the first screen of websites working on Android and iOS platform. Not only does VasSonic supports the static or dynamic websites which are rendered by server, but it is also compatible with web offline resource perfectly. VasSonic uses custom url connection instead of original network connection to request the index html, so it can request resource in advance or parallel to avoid waiting for the view initialization. In this parallel case, VasSonic can read and render partial data by WebKit or Blink kernel without spending too much time waiting for the end of data stream.

    Vespa

    Vespa

    The open big data serving engine

    Make AI-driven decisions using your data, in real-time. At any scale, with unbeatable performance. Vespa is a full-featured text search engine and supports both regular text search and fast approximate vector search (ANN). This makes it easy to create high-performing search applications at any scale, whether you want to use traditional techniques or a modern vector-based approach. You can even combine both approaches efficiently in the same query, something no other engine can do. Recommendation, personalization and targeting involves evaluating recommender models over content items to select the best ones. Vespa lets you build applications which does this online, typically combining fast vector search and filtering with evaluation of machine-learned models over the items. This makes it possible to make recommendations specifically for each user or situation, using completely up to date information.
