Dragonfly
DragonflyDB
Dragonfly is a drop-in Redis replacement that cuts costs and boosts performance. Designed to fully utilize the power of modern cloud hardware and deliver on the data demands of modern applications, Dragonfly frees developers from the limits of traditional in-memory data stores. The power of modern cloud hardware can never be realized with legacy software. Dragonfly is optimized for modern cloud computing, delivering 25x more throughput and 12x lower snapshotting latency when compared to legacy in-memory data stores like Redis, making it easy to deliver the real-time experience your customers expect. Scaling Redis workloads is expensive due to their inefficient, single-threaded model. Dragonfly is far more compute and memory efficient, resulting in up to 80% lower infrastructure costs. Dragonfly scales vertically first, only requiring clustering at an extremely high scale. This results in a far simpler operational model and a more reliable system. -

Sphinx
Sphinx
Sphinx is an open source full text search server, designed from the ground up with performance, relevance (aka search quality), and integration simplicity in mind. It's written in C++ and works on Linux (RedHat, Ubuntu, etc), Windows, MacOS, Solaris, FreeBSD, and a few other systems. Sphinx lets you either batch index and search data stored in an SQL database, NoSQL storage, or just files quickly and easily, or index and search data on the fly, working with Sphinx pretty much as with a database server. A variety of text processing features enable fine-tuning Sphinx for your particular application requirements, and a number of relevance functions ensures you can tweak search quality as well. Searching via SphinxAPI is as simple as 3 lines of code, and querying via SphinxQL is even simpler, with search queries expressed in good old SQL. Sphinx indexes up to 10-15 MB of text per second per single CPU core, that is 60+ MB/sec per server (on a dedicated indexing machine). -

livegrep
livegrep
Livegrep is a tool, partially inspired by Google Code Search, for interactive regex search of ~gigabyte-scale source repositories. To run livegrep, you need to invoke both the codesearch backend index/search process, and the livegrep web interface. To run the sample web interface over livegrep itself, once you have built both codesearch and livegrep. The codesearch binary is responsible for reading source code, maintaining an index, and handling searches. livegrep is stateless and relies only on the connection to codesearch over a TCP connection. By default, codesearch will build an in-memory index over the repositories specified in its configuration file. You can, however, also instruct it to save the index to a file on disk. This has the dual advantages of allowing indexes that are too large to fit in RAM, and of allowing an index file to be reused. -

Indexed Finance
Indexed Finance
Indexed Finance is a project focused on the development of passive portfolio management strategies for the Ethereum network. Indexed Finance is managed by the holders of its governance token NDX, which is used to vote on proposals for protocol updates and high level index management such as the definition of market sectors and the creation of new management strategies. The first product developed by Indexed Finance is a set of capitalization-weighted index pools designed to replicate the behavior of index funds, which historically have returned better and more consistent returns than actively managed funds on the stock market. Index pools simplify asset management on Ethereum the way that index funds do for the stock market: by creating a single asset which represents ownership in a diverse portfolio that tracks the market sector the index represents. Each index pool has an ERC20 index token (DEFI5 or CC10) which anyone can mint by providing the underlying assets in the pool. -
