Samples slow-running sorted set commands and identifies memory-heavy leaderboard keys without stalling the single-threaded Redis event loop.

# 1. Fetch the 10 slowest executing commands from Redis slowlog
redis-cli -h $REDIS_HOST -p $REDIS_PORT SLOWLOG GET 10

# 2. Non-blocking key sampling to isolate large sorted sets and hot keys
redis-cli -h $REDIS_HOST -p $REDIS_PORT --bigkeys

# 3. Inspect memory usage and encoding for tournament leaderboard key
redis-cli -h $REDIS_HOST -p $REDIS_PORT MEMORY USAGE leaderboard:season_global:top100

Identifies blocking transaction PIDs and maps row-level lock contention on player wallet tables without acquiring shared catalog locks.
