How does mcrouter work?
Destination health monitoring and automatic failover: Mcrouter keeps track of the health status of each destination. If mcrouter marks a destination as unresponsive, it will fail over incoming requests to an alternate destination automatically (fast failover) without attempting to send them to the original destination.
What is difference between Memcache and Redis?
Although they are both easy to use and offer high performance, there are important differences to consider when choosing an engine. Memcached is designed for simplicity while Redis offers a rich set of features that make it effective for a wide range of use cases.
Which is better Memcached or Redis?
Redis uses a single core and shows better performance than Memcached in storing small datasets when measured in terms of cores. Memcached implements a multi-threaded architecture by utilizing multiple cores. Therefore, for storing larger datasets, Memcached can perform better than Redis.
Is Redis same as Memcached?
Memcached is designed for simplicity while Redis offers a rich set of features that make it effective for a wide range of use cases. Understand your requirements and what each engine offers to decide which solution better meets your needs.
Why do we use memcache?
Memcached can serve cached items in less than a millisecond, and enables you to easily and cost effectively scale for higher loads. Memcached is popular for database query results caching, session caching, web page caching, API caching, and caching of objects such as images, files, and metadata.
Is MongoDB faster than Redis?
Redis is faster than MongoDB because it’s an in-memory database. This makes it a great choice for building complicated data structures quickly.
Does Google use Redis?
It’s fully managed. Google fully manages administrative tasks for Redis instances such as hardware provisioning, setup and configuration management, software patching, failover, monitoring and other nuances that require considerable effort for service owners who just want to use Redis as a memory store or a cache.
Can MongoDB replace Redis?
MongoDB is schemaless, which means that the database does not have a fixed data structure. This means that as the data stored in the database gets larger and larger, MongoDB is able to operate much faster than Redis. Redis is only significantly faster when the stored data is relatively small in size.
How do I enable replication on a virtual machine?
In the vault > Replicated Items, click the VM to which you added the disk. Click Disks, and then select the data disk for which you want to enable replication (these disks have a Not protected status). In Disk Details, click Enable replication.
How do I enable disk replication in Windows Server 2003?
Click Disks, and then select the data disk for which you want to enable replication (these disks have a Not protected status). In Disk Details, click Enable replication. After the enable replication job runs, and the initial replication finishes, the replication health warning for the disk issue is removed.
How do I replicate a virtual machine in a resource group?
Resource Group: The resource group to which your source virtual machines belong. All the VMs under the selected resource group are listed for protection in the next step. In Virtual Machines > Select virtual machines, click and select each VM that you want to replicate. You can only select machines for which replication can be enabled.
What does the “replication health” warning mean?
Replication health for the VM shows a warning, and a note informs telling you that one or more disks are available for protection. If you enable protection for the added disks, the warning will disappear after the initial replication of the disk. If you choose not to enable replication for the disk, you can select to dismiss the warning.
