Database Performance Tuning

Understands basic 1C:Enterprise query console usage for identifying slow queries. Can analyze simple query plans and recognize full table scans on register tables. Knows how to use temporary tables to avoid repeated calculations and follows established guidelines for writing performant queries in the 1C query language.

Monitors basic database performance metrics such as query execution time, buffer pool hit ratio, and connection counts. Can run EXPLAIN on slow queries and interpret simple query plans. Understands the purpose of VACUUM and ANALYZE operations and follows runbooks for routine maintenance tasks including index rebuilds and statistics updates.

Writes basic database queries for player state persistence and understands how to avoid blocking game loop threads with synchronous database calls. Can implement simple leaderboard queries with proper indexing and follows team patterns for batching inventory update operations to reduce round-trip latency to the database layer.

Profiles and optimizes 1C:Enterprise queries using the query console and technological log. Redesigns register table queries to leverage indexes effectively and reduces temporary table overhead in batch operations. Identifies N+1 query patterns in business logic and resolves lock contention issues during document posting by restructuring data access sequences.

Tunes buffer pool size, connection pool parameters, and write-ahead log configuration for production workloads. Performs detailed query plan analysis to eliminate inefficient joins, sequential scans, and suboptimal index usage. Configures automated vacuum schedules and analyzes replication lag to ensure read replicas stay within acceptable thresholds for application SLAs.

Optimizes player state persistence pipelines using write-behind caching and delta-based save strategies to minimize database load. Designs efficient leaderboard queries with materialized rankings that handle thousands of concurrent score updates. Implements real-time inventory transaction systems with optimistic locking and conflict resolution for simultaneous item modifications.
