-**Analysis:** ⚠️ **Needs Improvement**
-- Uses `insertMany()` which is correct, but missing options

+Based on this analysis, all samples are now using optimal bulk operation methods:

+1. ✅ **vector-search-java** - Updated in this PR with unordered insert options and improved error handling
+2. ✅ **vector-search-agent-go** - Updated in this PR with unordered insert options and improved error handling
+
+All samples now use optimal bulk operation methods with proper retry logic, error handling, and parallel execution capabilities.
+
+## Summary
+
+This PR provides a comprehensive analysis of MongoDB drivers and bulk insert methods across all samples in the `./ai` directory, and updates samples that were not using optimal bulk operation methods.
+
+### Changes Made
+
+1. **Created comprehensive analysis document** (`BULK_OPERATION_ANALYSIS.md`)
+   - Analyzed 7 samples across 5 programming languages
+   - Documented driver versions, insert methods, and best practices
+   - Identified which samples needed updates
+
+2. **Updated Java samples** (vector-search-java)
+   - Updated all 3 Java samples (HNSW.java, IVF.java, DiskAnn.java)
+   - Added `InsertManyOptions().ordered(false)` for parallel execution
+   - Added `MongoBulkWriteException` error handling
+   - Added tracking and logging of partial successes
+
+3. **Updated Go agent sample** (vector-search-agent-go)
+   - Updated `internal/vectorstore/store.go`
+   - Added `options.InsertMany().SetOrdered(false)` for parallel execution
+   - Added `mongo.BulkWriteException` error handling
+   - Added tracking and logging of partial insertions
 
-1. **vector-search-java** - Add unordered insert options and improved error handling
-2. **vector-search-agent-go** - Add unordered insert options
+### Summary of Findings
 
-All other samples are using optimal bulk operation methods and do not require updates.
+**Samples already using optimal methods (no changes needed):**
+- ✅ vector-search-python: Uses `bulk_write()` with `ordered=False`
+- ✅ vector-search-typescript: Uses `insertMany()` with `ordered: false`
+- ✅ vector-search-go: Uses `InsertMany()` with `SetOrdered(false)`
+- ✅ vector-search-dotnet: Uses `InsertManyAsync()` with `IsOrdered = false`
+- ✅ vector-search-agent-ts: Uses LangChain abstraction with optimal settings
 
-## Next Steps
+**Samples updated in this PR:**
+- ✅ vector-search-java: Now uses `insertMany()` with `ordered(false)` and error handling
+- ✅ vector-search-agent-go: Now uses `InsertMany()` with `SetOrdered(false)` and error handling
 
-1. Create a PR for **vector-search-java** to update insert method with proper options
-2. Create a PR for **vector-search-agent-go** to update insert method with proper options
-3. Update sample READMEs with bulk operation best practices guidance
+All samples now use optimal bulk operation methods that support:
+- Unordered inserts for parallel execution
+- Automatic retry logic for transient failures
+- Proper error handling with partial success tracking
+- Connection pooling and resource management
