-- Jellyfin PostgreSQL Migration

-- Migration: 20260227000000_AddSupplementaryIndexes

|
-- Purpose: Add performance indexes for improved query performance

-- ================================================

|
|
-- INSTRUCTIONS:
|
|
-- 1. Connect to your Jellyfin PostgreSQL database
|
|
-- 2. Run this script using psql, pgAdmin, or any PostgreSQL client
|
|
-- 3. Verify indexes are created (see verification query at end)

|
|
-- ================================================
|
|
|
|
-- 1. Composite index for filtered library browsing (type + virtual + parent)
|
|
-- Use case: Browse items by type in a specific library, excluding virtual items
|
|
-- Improves queries like: "SELECT * FROM BaseItems WHERE Type='Movie' AND IsVirtualItem=false AND TopParentId='xyz'"
|
|
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_baseitems_type_isvirtualitem_topparentid
|
|
ON library."BaseItems" ("Type", "IsVirtualItem", "TopParentId")
|
|
WHERE "IsVirtualItem" = false;
|
|
|
|
-- 2. Index for folder hierarchy queries
|
|
-- Use case: Navigate folder structures efficiently
|
|
-- Improves queries like: "SELECT * FROM BaseItems WHERE TopParentId='xyz' AND IsFolder=true"
|
|
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_baseitems_topparentid_isfolder
|
|
ON library."BaseItems" ("TopParentId", "IsFolder", "IsVirtualItem")
|
|
WHERE "TopParentId" IS NOT NULL;
|
|
|
|
-- 3. Index for recently added content with filters
|
|
-- Use case: "Recently Added" view across all libraries
|
|
-- Improves queries like: "SELECT * FROM BaseItems WHERE IsVirtualItem=false ORDER BY DateCreated DESC"
|
|
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_baseitems_datecreated_filtered
|
|
ON library."BaseItems" ("DateCreated" DESC, "Type", "IsVirtualItem")

|

|
|
|
|
-- 4. Index for reverse lookup (find items by genre/tag)
|
|
-- Use case: "Show all items with genre 'Action'"
|
|
-- Improves queries like: "SELECT ItemId FROM ItemValuesMap WHERE ItemValueId='action-genre-id'"
|
|
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_itemvaluesmap_itemvalueid_itemid
|
|
ON library."ItemValuesMap" ("ItemValueId", "ItemId");
|
|
|
|
-- 5. Index for user-specific activity queries
|
|
-- Use case: "Show activity for user X"
|
|
-- Improves queries like: "SELECT * FROM ActivityLogs WHERE UserId='user-id' ORDER BY DateCreated DESC"
|
|
-- Note: This will fail gracefully if the activitylog.ActivityLogs table doesn't exist
|
|

|
|
|
-- 6. Index for episode deduplication by PresentationUniqueKey
|
|
-- Use case: Group and deduplicate episodes (used in GetItems queries)
|
|
-- Improves queries like: "SELECT * FROM BaseItems WHERE Type='Episode' AND PresentationUniqueKey='xyz'"
|
|
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_baseitems_presentationuniquekey_episodes
