InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Various links on that page (e.g. https://www.dmi.unict.it/~faro/smart/howto.php) are dead for me, and browsing the source isn’t easy because they release .zip/.tar.gz. files (https://github.com/smart-tool/smart/releases), but theoretical algorithms often count character or byte comparisons, not nanoseconds. For the latter, code size and cache-friendliness matter, and the best code almost always must be tuned for one specific CPU, nowadays one specific state of a CPU (do you assume the SIMD hardware is powered up? If it isn’t, is using SIMD for short strings worth it?)
There probably also is a choice to be made as to what cases to optimize most for: length of search string, length of to-be-searched for string, case-sensitivity, diacritics-sensitivity, distribution of results (if, most of the time, the string is found close to the start, decreasing algorithm set up time at the cost of some speed may be worth it). ¿Are there corner cases where locale matters?
