    "incantation": "If the application needs an atomic window counter with bounds and expiration, evaluate Redis 8.8.0’s `INCREX` using an integer increment, an upper bound, and `ENX` with the window TTL.",
    "examples": [
      "INCREX <key> BYINT 1 UBOUND <limit> EX <seconds> ENX"
    ],
    "gotchas": [
      "Version: 8.8.0",
      "key (required): Key whose numeric value to increment.",
      "BYINT increment: Increment by a signed integer; defaults to 1 if no increment option is given. At most one of `BYINT` and `BYFLOAT` may be specified.",
      "BYFLOAT increment: Increment by a floating-point amount. At most one of `BYFLOAT` and `BYINT` may be specified.",
      "LBOUND lowerbound: Set the lower bound on the resulting value.",
      "UBOUND upperbound: Set the upper bound on the resulting value; an out-of-bound increment is skipped by default.",
      "SATURATE: Cap the result at the applicable bound instead of skipping an out-of-bound increment.",
      "EX seconds: Set expiration after a positive number of seconds. At most one expiration option may be specified: `EX`, `PX`, `EXAT`, `PXAT`, or `PERSIST`.",
      "PX milliseconds: Set expiration after a positive number of milliseconds. Mutually exclusive with the other expiration options.",
      "EXAT unix-time-seconds: Set expiration at a Unix timestamp in seconds. Mutually exclusive with the other expiration options.",
      "PXAT unix-time-milliseconds: Set expiration at a Unix timestamp in milliseconds. Mutually exclusive with the other expiration options.",
      "PERSIST: Remove the key’s expiration. Mutually exclusive with the other expiration options and incompatible with `ENX`.",
      "ENX: Apply the expiration only if the key currently has no TTL. Requires `EX`, `PX`, `EXAT`, or `PXAT`; incompatible with `PERSIST`.",
      "Prerequisite: Redis Open Source 8.8.0 or later; `INCREX` is available since 8.8.0."

  "why_it_matters": "Review whether a Redis-backed application’s rate-limiting logic can use the new window counter command.",
  "before": "The Redis feature issue describes the prior atomic approach as `SCRIPT LOAD` plus `EVALSHA`.",
