Description

Redis Open-Source Edition cloud native instances

• Standard architecture: up to 64 GB of memory and approximately 100,000 QPS.

• Read/write splitting architecture: up to 64 GB of memory and approximately 600,000 QPS.

• Cluster architecture: up to 16,384 GB (64 GB × 256 shards) of memory. Overall performance = number of shards × performance per shard, determined by shard specifications.

Redis Open-Source Edition classic instances

• Standard multi-replica instances use the master-replica architecture, with up to 64 GB of memory and approximately 80,000 QPS (reference value).

• Standard single-replica architecture: single-node Redis instances with up to 32 GB of memory and approximately 80,000 QPS (reference value).

• Cluster master-replica instances: each shard uses the master-replica architecture. Up to 4,096 GB (16 GB × 256 shards) of memory and approximately 25,600,000 QPS (reference value).

• Cluster single-replica architecture: each shard uses a single-node design. Up to 2,048 GB (16 GB × 128 shards) of memory and approximately 12,800,000 QPS (reference value).

• Read/write splitting instances consist of a master node and read replicas, with up to 64 GB of memory and approximately 600,000 QPS.

Retired instance types

Tair (Redis OSS-compatible) specific instance types are no longer available for purchase but remain usable. For specifications such as maximum connections, bandwidth, and QPS, see Retired instance types.

Description

Memory-optimized instance specifications

DRAM-based instances use a multi-threaded model, delivering approximately 3x the read/write performance of a same-spec Redis Open-Source Edition instance.

• Standard architecture: up to 64 GB of memory and approximately 300,000 QPS.

• Read/write splitting architecture: up to 64 GB of memory and approximately 1,800,000 QPS.

• Cluster architecture: up to 16,384 GB (64 GB × 256 shards) of memory. Overall performance = number of shards × performance per shard, determined by shard specifications.

DRAM-based instances also support the classic deployment mode.

• Standard master-replica architecture: multi-threaded, approximately 3x the performance of a same-spec Redis Open-Source Edition instance. Up to 64 GB of memory and approximately 240,000 QPS.

• Read/write splitting architecture: multi-threaded, with a master node and read replicas. Approximately 3x the performance of a same-spec Redis Open-Source Edition instance. Up to 64 GB of memory and approximately 1,440,000 QPS.

• Cluster architecture: multi-threaded, approximately 3x the performance of a same-spec Redis Open-Source Edition instance. Each shard uses master-replica architecture. Up to 4,096 GB (16 GB × 256 shards) of memory and approximately 61,440,000 QPS (reference value).

Persistent memory-optimized instance specifications

Persistent memory-optimized instances persist data without disks, delivering near-identical throughput and latency to Redis Open-Source Edition instances while persisting each operation. Standard instances offer up to 30% cost savings over Redis Open-Source Edition.

• Standard architecture: up to 64 GB of memory and approximately 100,000 QPS.

• Read/write splitting architecture: up to 64 GB of memory and approximately 600,000 QPS.

• Cluster architecture: up to 16,384 GB (64 GB × 256 shards) of memory. Overall performance = number of shards × performance per shard, determined by shard specifications.

Disk-based instance types

ESSD/SSD-based instances store data on disks with memory-accelerated caching, reducing costs by up to 85% compared with Redis Open-Source Edition at approximately 60% of the performance of Redis Open-Source Edition. Suitable for warm and cold data scenarios requiring Redis compatibility, large capacity, and high performance. Up to 32,768 GB (128 GB × 256 shards) of memory and 327,680 GB (1,280 GB × 256 shards) of standard storage.
