TEFD: A Benchmark for Natural Language to Flux Query Generation in Time-Series Databases

The proliferation of IoT and real-time monitoring has established Time-Series Databases (TSDBs) like InfluxDB as critical infrastructure. However, their functional query languages (e.g., Flux) present a steep learning curve, hindering data accessibility for non-experts. While Natural Language Interfaces (NLIs) offer a...
