I am new to aerospike DB. I inserted data from mysql to aerospike using a migration script. Due to some issue aerospike server was restarted.
But after the restart, there was no data in aerospike DB.
Can someone please let me know what could be the issue? Any config problem in Aerospike ?
What is the storage mechanism that you used with Aerospike? Did you use one of the default databases? One of the defaults is a in-memory only. Hence, data will be lost if it is an in-memory storage only with a single node and is restarted.
So basically you should ensure that the database storage is configured for persistence[1], has replication factor 2 or more and the suggested minimum number of servers in the cluster should be atleast equal to replication factor to ensure HA.
