Description

I mainly use a big map for each row in my hbase project. So my avro schema looks as follows:

{
"type": "record",
"name": "Request",
"namespace": "ch.test.generated",
"fields" : [
{
"name": "data",
"type":

{ "type": "map", "values": "long" }

}
]
}

As far as I could see the whole map is read from hbase whenever I get a row. Since I'm adding many map entries over time I would like to see some kind of lazy loading when accessing the map. A good place to specify this behavior would be the mapping file:

<gora-orm>
<class name="ch.test.generated.Request" keyClass="java.lang.Long" table="RequestLog">
<field name="data" family="dimension" lazy="true"/>
</class>
</gora-orm>
