问题 I was wondering how one would represent relationships in Aerospike ? I realize it's a Key-Value store but is there an example that can be given? For example: If have a user in the system and I want to get a list of Thing records associated with that user. 回答1: Couple of quick ideas: 1- Have each user be a record (equivalent of a row for conventional RDBMS) with multiple bins, each bin having the Primary Key of a 'Thing' Record in it. You can find more details about Aerospike's data model here

问题 I have so many records in aerospike, i want to fetch the records whose ttl is -1 please provide solution 回答1: Just to clarify, setting a TTL of -1 in the client means never expire (equivalent to a default-ttl of 0 in the server's aerospike.conf file), while setting a TTL of 0 in the client means inherit the default-ttl for this namespace . With Predicate Filtering: If you're using the Java, C, C# and Go clients the easiest way to identify the records with a void time of 0 would be to use a

问题 can i add aerospike cluster under aws autoscale? Like . my initial autoscale group size will 3, if more traffic comes in and if cpu utilization is greater then 80% then it will add another instance into the cluster. do you think it is possible? and does it has any disadvantage or will create any problem in cluster? 回答1: There's an Amazon CloudFormation script at aerospike/aws-cloudformation that gives an example of how to launch such a cluster. However, the point of autoscale is to grow

问题 I have an application with a high load for batch read operations. My Aerospike cluster (v 3.7.2) has 14 servers, each one with 7GB RAM and 2 CPUs in Google Cloud. By looking at Google Cloud Monitoring Graphs, I noticed a very unbalanced load between servers: some servers have almost 100% CPU load, while others have less than 50% (image below). Even after hours of operation, the cluster unbalanced pattern doesn't change. Is there any configuration that I could change to make this cluster more

问题 I am looking for distributed kv database for caching small binary objects, like images with TTL. Size limitation is not a problem, as I am planning to split each object anyway, to minimize latency. I need C# and Java drivers, and in very near future I will also need C++ driver. The databases like CouchDb and Redis seems to be document based. Mongo supports binary data and well documented, but it is persistent and I am not sure it is scalable in terms of throughput , Cassandra is also
