  2. Trie - Wikipedia

    en.wikipedia.org/wiki/Trie

    Each character in the string key set is represented via individual bits, which are used to traverse the trie over a string key. The implementations for these types of trie use vectorized CPU instructions to find the first set bit in a fixed-length key input (e.g. GCC 's __builtin_clz() intrinsic function ).

  8. B+ tree - Wikipedia

    en.wikipedia.org/wiki/B+_tree

    For string keys, space can be saved by using the following technique: Normally the i-th entry of an internal block contains the first key of block ⁠ + ⁠. Instead of storing the full key, we could store the shortest prefix of the first key of block ⁠ i + 1 {\displaystyle i+1} ⁠ that is strictly greater (in lexicographic order) than last ...

  9. API key - Wikipedia

    en.wikipedia.org/wiki/API_key

    API keys are generally not considered secure; they are typically accessible to clients, making it easy for someone to steal an API key. Once the key is stolen, it has no expiration, so it may be used indefinitely, unless the project ownerrevokes or regenerates the key.[2] Since API keys must only be accessible to the client and server ...
