GDS
A centralized reservation system that connects travel suppliers such as airlines and hotels with travel agents. Major providers include Amadeus, Sabre, and Travelport. GDS serves as the core B2B supply chain infrastructure in the traditional travel industry.

The page cache is the memory region the operating system kernel uses to cache file data; the GDS direct path typically bypasses the page cache (by opening files with O_DIRECT).
When using GDS, the target buffer must reside in GPU memory and meet alignment requirements (typically 4KB or larger), otherwise it falls back to a compatibility path.
GDS's benefits are most evident in scenarios such as large single-read data blocks, datasets far exceeding host memory capacity, the CPU concurrently handling other intensive tasks, and multiple GPUs loading the same storage pool in parallel.
For sequential large-block reads with no reuse, GDS offers clear advantages; for random small-file reads with hot data, the traditional cached path may be more suitable.
Before introducing GDS, one should first use a profiler to confirm that the bottleneck is on the data-loading side, then assess whether the storage devices and file system meet the prerequisites.
GDS (Global Distribution System) is an intermediary distribution network for travel products such as flights, hotels, and car rentals, with Amadeus, Sabre, and Travelport as the three major players.
The GDS look-to-book ratio can reach hundreds to one, and every query actually incurs supplier costs.
Direct airline access typically refers to obtaining real-time fares and inventory data through NDC interfaces or GDS platforms (such as Amadeus, Sabre, and Travelport) and holding authorization to book on behalf of customers.
A common characteristic of successful digital government cases is that design authority is deeply bound to government execution capabilities, rather than remaining at the front-end interface layer.
Applying consumer internet product methodologies to the government sector has precedents in cases such as the UK's GDS and Estonia's e-Estonia.
