Aerospike Replication Without Persistence

Will an in-memory only Aerospike cluster composed of n nodes automatically replicate data across nodes, and in this case, is there a guarantee that no data will be written to disk?

Solution

  • Will an in-memory only Aerospike cluster composed of n nodes automatically replicate data across nodes?

    Yes, assuming you are talking about storage-engine memory and not storage-engine device with data-in-memory true.

    And in this case, is there a guarantee that no data will be written to disk?

    Your records will not be written to disk. Logs and SMD (system meta data) will be written to disk.
