⚡️ Speed up method GDCFacetFilters.get_files_endpt_facet_filter by 14% in src/Connectors/gdc_filters.py

📄 GDCFacetFilters.get_files_endpt_facet_filter() in src/Connectors/gdc_filters.py

📈 Performance improved by 14% (0.14x faster)

⏱️ Runtime went down from 313 microseconds to 275 microseconds

Explanation and details

To optimize the given Python program for better runtime performance and memory usage, I'll consider the following strategies.

1. Inline Function Calls: By inlining the create_single_facet_filter function call within get_files_endpt_facet_filter, we can eliminate some overhead.
2. Reduce Dictionary Lookups: Perform dictionary lookups as minimally as possible.
3. Exception Handling: Instead of constructing an error message string when the key is not found, raise the ValueError directly.

Explanation

1. Inline Function Calls: By directly embedding the functionality of create_single_facet_filter inside get_files_endpt_facet_filter, we remove an extra function call, which is a small but real performance improvement.
2. Reduced Dictionary Lookups: Essential lookups are carried out only once, and the results are directly utilized, minimizing memory operations.
3. Exception Handling: Although exception construction was quite efficient, directly raising an error allows us to potentially skip creating an unnecessary error string in the case of a lookup failure.

Note that these changes are only minor optimizations; the initial code was already fairly efficient due to its straightforward logic. However, these tweaks could cumulatively improve performance slightly, especially when executed in tight loops or high-frequency calls.

Correctness verification

The new optimized code was tested for correctness. The results are listed below.
