Each edition provides different\nperformance and availability characteristics to meet the needs of your applications.\n\n- **Cloud SQL Enterprise edition**: provides all core capabilities of Cloud SQL and is suitable for applications requiring a balance of performance, availability, and cost.\n- **Cloud SQL Enterprise Plus edition**: provides the best performance and availability to run applications requiring the highest level of availability and performance in addition to the capabilities of the Cloud SQL Enterprise edition.\n\n| **Note:** Cloud SQL Enterprise edition supports all existing capabilities of Cloud SQL available as of July 12, 2023, at the same price. All existing instances before the launch of Cloud SQL editions on July 12, 2023 are updated to a Cloud SQL Enterprise edition instance automatically.\n\nCloud SQL editions features\n\nThe following table provides an overview of the features available for each edition:\n\n| | **Cloud SQL Enterprise edition** | **Cloud SQL Enterprise Plus edition** |\n|-------------------------------------------------------------------------------------------|-----------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| **[Pricing model](/sql/pricing)** | Cloud SQL Enterprise pricing | Cloud SQL Enterprise Plus pricing |\n| **[Database versions](/sql/docs/db-versions)** | MySQL 5.6, 5.7, 8.0, 8.4 | MySQL 8.0, 8.4 | **Note:** If the database version for your instance is MySQL 8.4, then the default Cloud SQL edition is Enterprise Plus. |\n| **[Machine series](/sql/docs/mysql/machine-series-overview)** | Shared or dedicated core | N2 C4A |\n| **[Machine configuration limits](/sql/docs/mysql/instance-settings#machine-type-2ndgen)** | Up to 96 vCPU Up to 624 GB RAM 1:6.5 core:memory ratio | **N2 machine series** Up to 128 vCPU Up to 864 GB RAM 1:8 core:memory ratio **C4A machine series** (Preview) Up to 72 vCPU Up to 576 GB RAM 1:8 core:memory ratio |\n| **[Availability SLA](/sql/sla)** | 99.95% | 99.99% |\n| **[Maintenance downtime](/sql/docs/mysql/maintenance)** | [\\\u003c 60 seconds](/sql/docs/mysql/maintenance#maintenance-impact) | [\\\u003c 1 second](/sql/docs/mysql/maintenance#nearzero) |\n| **[Data cache](/sql/docs/mysql/data-cache)** | No | Yes |\n| **[Point-in-time log retention](/sql/docs/mysql/backup-recovery/pitr)** | Up to 7 days | Up to 35 days |\n\nPerformance enhancements\n\nCloud SQL for MySQL Enterprise Plus edition delivers enhanced read and write performance, and is\nideal for applications that require maximum performance. This edition offers the following enhancements:\n\n- **Improved read performance using data cache**: Data cache leverages a fast,\n local SSD to store data pages that are read frequently. You can get up to\n three times improvement in read performance compared to reading from a\n persistent disk. Data cache is an optional feature and can be\n enabled during instance creation or after the instance has been created.\n\n- **Enhanced write performance**: Cloud SQL Enterprise Plus edition delivers up to two times the\n improvement in write latency. This makes it suitable for write-intensive applications requiring low latency and high throughput.\n\n- **Engine autotuning**: autotune engine configurations to match the\n capabilities of the underlying instance platform.\n\nAvailability enhancements\n\nCloud SQL Enterprise Plus edition provides the following major availability enhancements:\n\n- **Advanced disaster recovery (DR)**: you can simplify recovery and fallback\n processes after you perform cross-region failover. With advanced DR, you\n can:\n\n - Choose a cross-region disaster recovery (DR) replica\n\n - Perform replica failover\n\n - Restore your original deployment by using zero data loss switchover\n\n For more information, see [Advanced disaster recovery (DR)](/sql/docs/mysql/intro-to-cloud-sql-disaster-recovery#advanced-dr)\n and [Use advanced disaster recovery (DR)](/sql/docs/mysql/use-advanced-disaster-recovery).\n\n\u003c!-- --\u003e\n\n- **Near-zero downtime**: with Cloud SQL Enterprise Plus edition, you can maintain near-zero\n downtime for your instance when you perform any of the following management\n tasks:\n\n - Perform or simulate a [planned maintenance update event](/sql/docs/mysql/maintenance#nearzero) on\n a standalone primary instance\n\n - Enable or disable [data cache](/sql/docs/mysql/data-cache)\n\n - Scale up the compute size (vCPU, memory) of your Cloud SQL instance\n as many times you like\n\n - Scale down the compute size (vCPU, memory) of your Cloud SQL instance\n once every three hours\n\n | **Note:** If you scale down your instance more than once during a three-hour period, then only the first scale down event benefits from near-zero downtime. Subsequent scale down events experience regular downtime.\n - Perform an [in-place upgrade to Cloud SQL Enterprise Plus edition](/sql/docs/mysql/upgrade-cloud-sql-instance-to-enterprise-plus-in-place)\n\n - For Cloud SQL for MySQL 8.0 instances, perform an [in-place minor version upgrade](/sql/docs/mysql/upgrade-minor-db-version)\n\n \u003cbr /\u003e\n\nCloud SQL region support\n\nFor more information about Cloud SQL regions, see\n[Region availability overview](/sql/docs/mysql/region-availability-overview).\n\nPricing\n\nFor more information about Cloud SQL editions pricing, see\n[Cloud SQL pricing](/sql/pricing).\n\nCloud SQL editions FAQs\n\nThis section provides answers to frequently asked questions\nabout Cloud SQL editions.\n\nDoes Cloud SQL Enterprise Plus edition support all engines?\n\nYes.
