# memorydb ## Description MemoryDB is a fully managed, Redis OSS-compatible, in-memory database that delivers ultra-fast performance and Multi-AZ durability for modern applications built using microservices architectures. MemoryDB stores the entire database in-memory, enabling low latency and high throughput data access. It is compatible with Redis OSS, a popular open source data store, enabling you to leverage Redis OSS’ flexible and friendly data structures, APIs, and commands. ## Available Commands * [batch-update-cluster](batch-update-cluster.md) * [copy-snapshot](copy-snapshot.md) * [create-acl](create-acl.md) * [create-cluster](create-cluster.md) * [create-multi-region-cluster](create-multi-region-cluster.md) * [create-parameter-group](create-parameter-group.md) * [create-snapshot](create-snapshot.md) * [create-subnet-group](create-subnet-group.md) * [create-user](create-user.md) * [delete-acl](delete-acl.md) * [delete-cluster](delete-cluster.md) * [delete-multi-region-cluster](delete-multi-region-cluster.md) * [delete-parameter-group](delete-parameter-group.md) * [delete-snapshot](delete-snapshot.md) * [delete-subnet-group](delete-subnet-group.md) * [delete-user](delete-user.md) * [describe-acls](describe-acls.md) * [describe-clusters](describe-clusters.md) * [describe-engine-versions](describe-engine-versions.md) * [describe-events](describe-events.md) * [describe-multi-region-clusters](describe-multi-region-clusters.md) * [describe-multi-region-parameter-groups](describe-multi-region-parameter-groups.md) * [describe-multi-region-parameters](describe-multi-region-parameters.md) * [describe-parameter-groups](describe-parameter-groups.md) * [describe-parameters](describe-parameters.md) * [describe-reserved-nodes](describe-reserved-nodes.md) * [describe-reserved-nodes-offerings](describe-reserved-nodes-offerings.md) * [describe-service-updates](describe-service-updates.md) * [describe-snapshots](describe-snapshots.md) * [describe-subnet-groups](describe-subnet-groups.md) * [describe-users](describe-users.md) * [failover-shard](failover-shard.md) * [list-allowed-multi-region-cluster-updates](list-allowed-multi-region-cluster-updates.md) * [list-allowed-node-type-updates](list-allowed-node-type-updates.md) * [list-tags](list-tags.md) * [purchase-reserved-nodes-offering](purchase-reserved-nodes-offering.md) * [reset-parameter-group](reset-parameter-group.md) * [tag-resource](tag-resource.md) * [untag-resource](untag-resource.md) * [update-acl](update-acl.md) * [update-cluster](update-cluster.md) * [update-multi-region-cluster](update-multi-region-cluster.md) * [update-parameter-group](update-parameter-group.md) * [update-subnet-group](update-subnet-group.md) * [update-user](update-user.md)
