ZTSDB

ztsdb is a fast, small and lightweight multi-user noSQL column-store database management system designed and optimized for the update, storage and handling of time-series data. Its query and manipulation language is based on the R programming language and allows complex selections of data inside a time-series or across multiple time-series. It is free software licensed under the GPLv3... The following code can be run directly on the R command line. It creates a connection to a ztsdb instance and then uses the ? operator to execute the query on the connected instance. The results are translated to R types (in particular ztsdb time-series are translated to data.table-based time-series). Let's suppose that the time-series z in the previous example was created on a local instance listening on port 15001 and that it is populated with data... Mostly a subset of R, it should feel very familiar to R users. This example shows the creation of a persistent time-series (any ztsdb data object can..
