WebFeb 19, 2024 · datasketch gives you probabilistic data structures that can process and search very large amount of data super fast, with little loss of accuracy. The following indexes for data sketches are provided to support sub-linear query time: datasketch must be used with Python 2.7 or above, NumPy 1.11 or above, and Scipy. WebExtensions. Druid implements an extension system that allows for adding functionality at runtime. Extensions are commonly used to add support for deep storages (like HDFS and S3), metadata stores (like MySQL and PostgreSQL), new aggregators, new input formats, and so on. Production clusters will generally use at least two extensions; one for ...
