Hi, i do a migration from aws to google cloud, with same resorces.
But minha google sql is in 90% and on aws no transpass to 50%.
i think need set a sinalization or same someting else.
sinalizations:
There are several factors why you might be seeing higher CPU Spikes. Below are some Troubleshooting and optimizations options:
Performance Profiling: Leverage Cloud SQL's Query Insights and Cloud Monitoring to identify CPU-intensive queries and bottlenecks. Enabling the MySQL slow query log can also help capture long-running queries for further analysis.
Query Optimization: Focus on refining slow-running queries by:
Enhancing index usage.
Rewriting inefficient queries.
Reducing unnecessary full table scans.
Configuration Review: Adjust Cloud SQL-specific parameters based on performance insights. Important parameters affecting performance include:
innodb_buffer_pool_size
: Controls the size of the buffer pool, which caches data and indexes in memory.
max_connections
: Determines the maximum number of simultaneous client connections.
Thread and connection management settings to optimize server resource usage.
Workload Adjustments: Consider strategies like using read replicas to distribute read-heavy workloads and implementing a caching layer (e.g., Redis, Memcached) to reduce direct database queries.
Serializations and Configuration Parameters
While parameters like log_bin_trust_function_creators
and sql_mode
might not directly impact CPU usage, they influence database behavior and performance. For example, sql_mode
can affect how certain queries are executed, potentially impacting CPU indirectly.
Additional Considerations
Cloud SQL Insights: Utilize Cloud SQL Insights for detailed query performance analysis, which can help in identifying and diagnosing issues related to high CPU usage.
Version Compatibility: Ensure MySQL versions are compatible or identical between AWS RDS and Google Cloud SQL to avoid performance issues stemming from differences in database engine optimizations and configurations.
