From 322dca463b02f37f6486805ab3f415e6a99e1c25 Mon Sep 17 00:00:00 2001 From: Himanth-reddy <176995830+Himanth-reddy@users.noreply.github.com> Date: Sun, 5 Apr 2026 05:10:21 +0000 Subject: [PATCH 01/12] =?UTF-8?q?=E2=9A=A1=20Optimize=20redundant=20Season?= =?UTF-8?q?=20API=20calls=20in=20TraktRepository?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 💡 What: Implemented an ephemeral cache (ConcurrentHashMap) during the parallel Continue Watching enrichment loops in TraktRepository.kt. The cache ensures that if multiple episodes of the same season are queried simultaneously, only one API call goes out and the other queries await the result. 🎯 Why: Previously, enrichContinueWatchingItems fetched season information via tmdbApi.getTvSeason() for every Continue Watching item synchronously inside its coroutine. In scenarios where a user is re-watching or has multiple items from the same season of a show, it fired identical network calls concurrently leading to unnecessary network/CPU utilization. 📊 Measured Improvement: Due to difficulties instantiating TraktRepository without Roboelectric or extensive mocks of DataStore, I have skipped creating a formal Android benchmark test suite instance to measure this precisely in CI. However, logically, a user with N items of the same season went from O(N) API calls down to O(1), removing network roundtrip overhead entirely for N-1 items during parallel awaitAll() execution. --- .../tv/data/repository/TraktRepository.kt | 30 ++++++++++++++----- .../TraktRepositoryBenchmarkTest.kt | 14 +++++++++ 2 files changed, 36 insertions(+), 8 deletions(-) create mode 100644 app/src/test/kotlin/com/arflix/tv/data/repository/TraktRepositoryBenchmarkTest.kt diff --git a/app/src/main/kotlin/com/arflix/tv/data/repository/TraktRepository.kt b/app/src/main/kotlin/com/arflix/tv/data/repository/TraktRepository.kt index 91d29f386..f9e80f15c 100644 --- a/app/src/main/kotlin/com/arflix/tv/data/repository/TraktRepository.kt +++ b/app/src/main/kotlin/com/arflix/tv/data/repository/TraktRepository.kt @@ -27,6 +27,7 @@ import io.github.jan.supabase.postgrest.Postgrest import io.github.jan.supabase.postgrest.postgrest import kotlinx.coroutines.Dispatchers import kotlinx.coroutines.async +import kotlinx.coroutines.Deferred import kotlinx.coroutines.awaitAll import kotlinx.coroutines.coroutineScope import kotlinx.coroutines.flow.Flow @@ -1796,10 +1797,11 @@ class TraktRepository @Inject constructor( // Enrich items with TMDB data in parallel (limited concurrency) val semaphore = kotlinx.coroutines.sync.Semaphore(5) + val seasonCache = java.util.concurrent.ConcurrentHashMap, Deferred>() rawItems.map { item -> async { semaphore.withPermit { -

Wrapped the network requests with a Semaphore(5) to bound concurrency to 5 parallel requests. Why: The previous implementation was suffering from an N+1 Database Operation loop. For each stale record, it performed a sequential network request (supabaseApi.deleteWatchHistory) to Supabase. This resulted in significant I/O delays proportional to the number of stale records. Measured Improvement: Simulated a 75ms network latency for the Supabase network call across 50 stale playback records in a benchmark test. Baseline (Sequential time): ~3766ms. Improved (Concurrent time with Semaphore 5): ~754ms.
