Complex Attribute Queries with Multiple JOINs + +The `attributesSelect` function creates queries with: +- 5-7 LEFT JOINs +- JSON aggregations +- GROUP BY operations +- Nested subqueries + +**Example Pattern:** +```sql +SELECT + ad.id, ad.name, ad.rule, + JSON_AGG(JSON_BUILD_OBJECT(...))

The subquery joining `attribute_values` with `attribute_value_members` needs: + ```sql + CREATE INDEX idx_value_members_lookup + ON attribute_value_members(value_id, member_id); + ``` + +2. For the JSON aggregation performance: + ```sql + CREATE INDEX idx_attribute_values_definition_active + ON attribute_values(attribute_definition_id, active, id) + INCLUDE (value, members); + ``` + +### 2. Subject Mapping Queries with Condition Sets + +The `subjectMappingSelect` function has: +- Complex JSON_BUILD_OBJECT operations +- Multiple GROUP BY clauses +- JSONB condition field access + +**Optimization Needed:** +```sql +-- For the subject condition lookup +CREATE INDEX idx_subject_condition_lookup +ON subject_condition_set(id) +INCLUDE (condition); + +-- For the subject mapping joins +CREATE INDEX idx_subject_mappings_joins +ON subject_mappings(attribute_value_id, subject_condition_set_id); +``` + +### 3. FQN (Fully Qualified Name) Lookups + +When `withOneValueByFqn` is used, queries include: +```sql +INNER JOIN attribute_fqns AS inner_fqns ON av.id = inner_fqns.value_id +WHERE inner_fqns.fqn = 'namespace/attribute/value' +``` + +**Critical Index:** +```sql +-- This is the most important index for FQN lookups +CREATE UNIQUE INDEX idx_fqn_lookup_unique +ON attribute_fqns(fqn) +INCLUDE (namespace_id, attribute_id, value_id); +``` + +### 4. Active Record Filtering Pattern + +Almost every query includes `WHERE active = true`: + +**Partial Index Strategy:** +```sql +-- Create partial indexes for all active record queries +CREATE INDEX idx_attribute_definitions_active_partial +ON attribute_definitions(namespace_id, id) +WHERE active = true; + +CREATE INDEX idx_attribute_values_active_partial +ON attribute_values(attribute_definition_id, id) +WHERE active = true; +``` + +## Query Rewriting Recommendations + +### 1. Avoid Nested Subqueries in JOINs + +Instead of: +```sql +LEFT JOIN (SELECT ... GROUP BY ...) subquery ON ... +``` + +Consider using CTEs: +```sql +WITH value_members_agg AS ( + SELECT value_id, JSON_AGG(...) as members + FROM attribute_value_members + GROUP BY value_id +) +SELECT ... FROM attribute_definitions +LEFT JOIN value_members_agg ON ... +``` + +### 2. Use FILTER Clause for Conditional Aggregation + +Current pattern: +```sql +COALESCE(JSON_AGG(...) FILTER (WHERE vmv.id IS NOT NULL), '[]') +``` + +This is good! The FILTER clause is more efficient than using CASE statements. + +### 3. Consider Materialized Views for Complex Aggregations + +For frequently accessed complex queries, create materialized views: + +```sql +CREATE MATERIALIZED VIEW mv_attribute_with_values AS +SELECT + ad.id, + ad.namespace_id, + ad.name, + ad.active, + JSON_AGG( + JSON_BUILD_OBJECT( + 'id', av.id, + 'value', av.value, + 'active', av.active + ) + ) AS values +FROM attribute_definitions ad +LEFT JOIN attribute_values av ON av.attribute_definition_id = ad.id +WHERE ad.active = true +GROUP BY ad.id; + +CREATE UNIQUE INDEX ON mv_attribute_with_values(id); +CREATE INDEX ON mv_attribute_with_values(namespace_id); + +-- Refresh periodically or on data changes +REFRESH MATERIALIZED VIEW CONCURRENTLY mv_attribute_with_values; +``` + +## Application-Level Optimizations + +### 1. Implement Query Result Caching + +For frequently accessed, relatively static data: +```go +// Cache attribute definitions with values for 5 minutes +type AttributeCache struct { + data map[string]*policy.Attribute + ttl time.Duration +} +``` + +### 2. Use Prepared Statements + +Modify the query builders to use prepared statements: +```go +stmt, err := db.Prepare(ctx, "get_attr_by_fqn", query) +// Reuse the prepared statement +``` + +### 3.
