Subject: [PATCH] Optimize bit_set_int
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The optimization achieves a **14% runtime improvement** (397μs → 346μs) by eliminating repeated attribute lookups on every function call.

**What changed:**
The code now caches `aerospike.OP_BIT_SET_INT` as a module-level constant `_OP_BIT_SET_INT` instead of looking it up from the `aerospike` module each time `bit_set_int()` is called.

**Why this is faster:**
In Python, attribute access (like `aerospike.OP_BIT_SET_INT`) involves dictionary lookups in the module's namespace on every access. By pre-computing this value once at module import time, the function uses a simple local variable lookup instead—a significantly cheaper operation. The line profiler confirms this: the dictionary construction line that previously showed 474522ns for the `OP_KEY` assignment now shows only 449181ns, a measurable reduction in overhead.

**Performance characteristics:**
The test results show consistent improvements across all test cases:
- Simple calls: 17-32% faster (e.g., `test_bin_name_is_stored_correctly`: 1.91μs → 1.44μs)
- Sequential calls benefit from the optimization on every iteration (e.g., 100 sequential calls: 45.4μs → 41.4μs, 9.7% faster)
- The improvement scales well with call frequency—functions called in tight loops or hot paths see compounding benefits

**Impact on workloads:**
Since `bit_set_int()` is a helper that constructs operation dictionaries for Aerospike database operations, it's likely called frequently when building batch operations or in data processing pipelines. The 14% speedup means less overhead when constructing large numbers of bitwise operations, making it particularly valuable in high-throughput scenarios where operations are assembled in bulk.
