I need to save the following format in Aerospike:
```
{"name": "interest",
"datamap" : [
{"sports":"soccer"},
{"color":"green"}],
"clientId":"100",
"eventTagId": 78932
}
```
Here `clientId` is a key. I can save `name: interest` for a single key(`clientId`) as ‘name’ will be the bin name and ‘interest’ will be its value. But, if I have a bin with multiple values for a single key like the following example:
```
datamap" : [
{"sports":"soccer"},
{"color":"green"}]
```
so how to store in Aerospike? I need a solution which does not give me hard time when I have to retrieve millions of records. I was thinking in a way to create another set for `datamap` with `clientId` as a key, and later perform JOIN operation on them. But I think it is an old relational DB solution. Your suggestions will be highly appreciated.

If that’s your data model I’d save it in a single record with the bins _name_, _datamap_, _clientId_, and _eventTagId_. Aerospike supports the [complex data types](https://www.aerospike.com/docs/guide/data-types.html#complex-data-types) list and map, and the data of _datamap_ is a map.
For example, this is how you do it in the Python client: [http://www.aerospike.com/docs/client/python/usage/kvs/write.html](http://www.aerospike.com/docs/client/python/usage/kvs/write.html)
Because this isn’t SQL-land, your data doesn’t need to be two-dimensional with a join connecting two tables in a many-to-one relationship. You just put complex data in the bin of your record, no JOIN needed.
