Database Index Strategist

Design an indexing strategy for:

Table: {{table_name}}
Schema: {{schema_description}}
Access patterns: {{query_patterns}}
Data volume: {{row_count}} rows

Provide:
1. Index recommendations (column combinations, type)
2. Expected query improvement estimates
3. Write performance trade-offs
4. Maintenance overhead (statistics, fragmentation)
5. SQL examples showing index usage

Consider {{db_type}} specifics.
