Dead tuples are outdated row versions that PostgreSQL keeps for MVCC (Multi-Version Concurrency Control) but are no longer accessible. Excessive dead tuples degrade query performance and waste disk space. + +## Problem Analysis + +Based on your database statistics, the following tables are generating significant dead tuples during media library scans: + +| Table | Dead Tuples | Dead % | Status | +|-------|-------------|--------|--------| +| BaseItemImageInfos | 4,036 | 4.19% | ⚠️ Moderate | +| Chapters | 1,659 | 4.30% | ⚠️ Moderate | +| MediaStreamInfos | 1,410 | 1.34% | ✓ OK | +| BaseItems | 2,229 | 1.63% | ✓ OK | +| BaseItemProviders | 1,654 | 0.64% | ✓ OK | +| PeopleBaseItemMap | 193 | 0.05% | ✓ OK | + +**Typical healthy threshold**: < 5% dead tuples + +### Root Causes + +1. **Frequent updates without batching**: Each item update creates a new row version, marking the old one as dead +2. **Individual SaveChanges() calls**: Multiple discrete transactions instead of batched operations +3. **Suboptimal autovacuum settings**: Default PostgreSQL autovacuum may not keep up during heavy scans +4. **High concurrency during scans**: Media library scans update many rows simultaneously + +## Implemented Optimizations + +### 1. Bulk Operation Extensions (`BulkOperationExtensions.cs`) + +Provides efficient methods for bulk operations: + +```csharp +// Automatic batch sizing based on workload +var batchSize = context.GetBatchSize(entityCount); + +// Bulk operations that save in batches +await context.BulkAddAsync(newItems, batchSize: 100, saveAfterEachBatch: true); +await context.BulkUpdateAsync(updatedItems, batchSize: 100); +await context.BulkRemoveAsync(deletedItems, batchSize: 100); + +// Save changes in batches to reduce dead tuples +await context.SaveChangesInBatchesAsync(batchSize: 100); + +// Direct SQL for maximum performance +await context.BulkDeleteAsync("library", "BaseItemImageInfos", "where condition"); +``` + +### 2. Batch Sizing Strategy + +The context provides intelligent batch sizing: + +- **< 100 items**: Batch of 10 (light operations) +- **100-1000 items**: Batch of 50 (medium operations) +- **1000-10000 items**: Batch of 100 (heavy operations) +- **> 10000 items**: Batch of 200 (very heavy operations) + +Smaller batches during scans mean more frequent commits and faster VACUUM cleanup of dead tuples. + +### 3. Transaction Management (`BulkOperationTransaction.cs`) + +Provides proper transaction scoping for bulk operations: + +```csharp +// Execute operation in transaction +await context.ExecuteBulkOperationAsync(async () => +{ + // Bulk operations here + await context.BulkUpdateAsync(items); +}); + +// With result +var result = await context.ExecuteBulkOperationAsync(async () => +{ + // Operations that return a result + return await context.SaveChangesAsync(); +}); +``` + +Uses `READ COMMITTED` isolation level - optimal for bulk operations as it: +- Minimizes lock contention +- Allows VACUUM to reclaim dead tuples more aggressively +- Maintains data integrity for bulk operations + +## PostgreSQL Configuration Recommendations + +### Critical Autovacuum Settings + +Add these to `postgresql.conf` or use `ALTER SYSTEM` commands: + +```sql +-- For library schema (heavy media scan activity) +ALTER SYSTEM SET autovacuum_vacuum_scale_factor = 0.01; -- Vacuum at 1% dead tuples +ALTER SYSTEM SET autovacuum_analyze_scale_factor = 0.005; -- Analyze at 0.5% dead tuples +ALTER SYSTEM SET autovacuum_vacuum_cost_delay = 5; -- ms between autovacuum work +ALTER SYSTEM SET autovacuum_vacuum_cost_limit = 1000;

-- % of system RAM +ALTER SYSTEM SET effective_cache_size = '50%'; -- % of system RAM for planner + +-- Reload configuration +SELECT pg_reload_conf(); +``` + +### Per-Table Autovacuum Tuning + +For tables with heavy churn (like BaseItemImageInfos): + +```sql +-- Connect to jellyfin database +\c jellyfin + +-- More aggressive autovacuum for high-churn tables +ALTER TABLE library.BaseItemImageInfos SET ( + autovacuum_vacuum_scale_factor = 0.005, + autovacuum_analyze_scale_factor = 0.0025, + autovacuum_vacuum_cost_delay = 2, + fillfactor = 80 +); + +ALTER TABLE library.Chapters SET ( + autovacuum_vacuum_scale_factor = 0.005, + autovacuum_analyze_scale_factor = 0.0025, + autovacuum_vacuum_cost_delay = 2, + fillfactor = 80 +); + +ALTER TABLE library.MediaStreamInfos SET ( + autovacuum_vacuum_scale_factor = 0.01, + autovacuum_analyze_scale_factor = 0.005, + autovacuum_vacuum_cost_delay = 5, + fillfactor = 80 +); +``` + +**Note on fillfactor**: Setting `fillfactor = 80` reserves 20% of each page for future updates, reducing the need for page splits. + +### Connection Pool Tuning + +The PostgreSQL provider now uses optimized connection settings: + +```csharp +// Configured in PostgresDatabaseProvider.cs +connectionBuilder = new NpgsqlConnectionStringBuilder +{ + MaxPoolSize = 100, // Reduced from unlimited + MinPoolSize = 0, // Dynamically grow pool + Multiplexing = false, // Better for bulk operations + CommandTimeout = 120, // 2 minutes for scans + ApplicationName = "jellyfin-mediaserver" +}; +``` + +## Usage Examples + +### Example 1: Bulk Update During Media Scan + +```csharp +public async Task UpdateMediaItemsAsync(IEnumerable items, CancellationToken cancellationToken) +{ + // Use bulk update with automatic batching + var batchSize = _context.GetBatchSize(items.Count()); + await _context.BulkUpdateAsync(items, batchSize, cancellationToken); +} +``` + +### Example 2: Bulk Delete with VACUUM + +```csharp +public async Task DeleteStaleItemsAsync(CancellationToken cancellationToken) +{ + await _context.ExecuteBulkOperationAsync(async () => + { + // Delete in a transaction + await _context.BulkDeleteAsync( + "library", + "BaseItemImageInfos", + "where LastModified < now() - interval '1 month'", + cancellationToken); + + // Reclaim space after bulk delete + await _context.VacuumTableAsync("library", "BaseItemImageInfos", cancellationToken); + }, cancellationToken); +} +``` + +### Example 3: Large Batch Insert + +```csharp +public async Task ImportNewItemsAsync(IEnumerable items, CancellationToken cancellationToken) +{ + // Batch add with progress + var totalAdded = await _context.BulkAddAsync( + items, + batchSize: 500, // Larger batches for inserts + saveAfterEachBatch: true, + cancellationToken); + + _logger.LogInformation("Added {Count} items", totalAdded); +} +``` + +## Monitoring Dead Tuples + +### Query to Check Current Status + +```sql +-- Run this periodically to monitor dead tuple growth +SELECT + schemaname, + tablename, + n_dead_tup as dead_tuples, + n_live_tup as live_tuples, + ROUND(n_dead_tup::float / (n_live_tup + n_dead_tup) * 100, 2) as dead_percent, + last_vacuum, + last_autovacuum, + last_analyze, + last_autoanalyze +FROM pg_stat_user_tables +WHERE schemaname = 'library' +ORDER BY n_dead_tup DESC;

+ +-- Check autovacuum settings for specific table +SELECT * FROM pg_class +WHERE relname = 'BaseItemImageInfos' + AND relnamespace = 'library'::regnamespace; +``` + +**Solution**: +1. Verify autovacuum is enabled: `SHOW autovacuum;` (should be `on`) +2. Manually run VACUUM: `VACUUM ANALYZE library.BaseItemImageInfos;` +3. Check PostgreSQL logs for autovacuum errors + +### Issue: Slow media library scans + +**Check**: +```sql +-- See current scan progress +SELECT pid, query_start, query FROM pg_stat_activity +WHERE query LIKE '%library%' AND state = 'active'; + +-- Check table bloat +SELECT + schemaname, + tablename, + pg_size_pretty(pg_total_relation_size(schemaname||'.'||tablename)) as size, + n_dead_tup +FROM pg_stat_user_tables +WHERE schemaname = 'library' +ORDER BY pg_total_relation_size(schemaname||'.'||tablename) DESC; +``` + +### Issue: Application deadlocks + +**Solutions**: +1. Increase `deadlock_timeout`: `ALTER SYSTEM SET deadlock_timeout = '10s';` +2. Reduce batch size in BulkOperationExtensions +3. Check for long-running transactions blocking other operations + +## Migration Guide + +### Updating Existing Code + +Old pattern (inefficient): +```csharp +foreach (var item in items) +{ + context.Update(item); + await context.SaveChangesAsync(); // ❌ One transaction per item +} +``` + +New pattern (optimized): +```csharp +// ✅ Single transaction with batching +await context.BulkUpdateAsync(items, batchSize: 100); +``` + +### Backward Compatibility + +All new methods are extension methods and helpers. Existing code continues to work unchanged.
