⚡ Bolt: optimize NA replacement and eliminate redundant API calls#179
Conversation
💡 What: 1. Replaced `ifelse()` with logical indexing for NA replacement in `combine_consumption()`. 2. Added `include_gsp` parameter to `get_meter_details()` to skip redundant GSP lookup API calls. 3. Updated `get_consumption()` to use `include_gsp = FALSE`. 4. Switched to `NA_character_` for type consistency in `gsp` field. 🎯 Why: `ifelse()` is inefficient for large vectors as it evaluates all branches and allocates more memory. `get_consumption()` was triggering a redundant API call to fetch GSP data which is not used by the function. 📊 Impact: - NA replacement is ~3x faster and uses ~3x less memory. - Redundant GSP lookup API call eliminated in `get_consumption()`, reducing network overhead. 🔬 Measurement: `bench::mark()` showed: - ifelse: 32.2ms, 53.4MB - logical_indexing: 11.8ms, 15.6MB Verified API call reduction with manual mocking of `octopus_api`.

Use an H1 on the first line to satisfy markdownlint.
This file currently starts with a level-2 heading, which is what CI is complaining about.

Honour include_gsp in the testing branch as well.
get_meter_details() now exposes include_gsp, but the is_testing() path still delegates to testing_meter() without that flag, and testing_meter() always derives electricity gsp. That leaves the redundant lookup in place for test/dev runs and makes the new parameter behave differently depending on the code path.

This PR implements two key performance optimizations in the
octopusRpackage:combine_consumption(), we now use logical indexing (x[is.na(x)] <- 0) instead ofifelse(is.na(x), 0, x). Benchmarking on 1M elements showed a ~3x speedup and significant reduction in memory allocation.get_meter_details()function was automatically callingget_meter_gsp()(an API call) even when the GSP was not needed. We introduced aninclude_gspparameter (defaultTRUEfor backward compatibility) and updatedget_consumption()to set it toFALSE. This eliminates one redundant API call every timeget_consumption()is called without explicit MPAN/Serial.Additionally, we improved type stability by using
NA_character_for thegspfield and updated the package documentation.All tests pass and
R CMD checkis clean.PR created automatically by Jules for task 11554196582224710021 started by @Moohan
