Re: Partition Id for a Data key in case of data colocation

What do you mean by "store the data in appropriate bucket"? Affinity key is used to locate the partition, but the (regular) key is used to store the entry itself, so entries don't override each other since each entry has a unique key. Stan prasadbhalerao1983 wrote > Hi, > > With affinity key ig

To specify a configuration parameter in the XML config you need to put the names of the properties in the tags, like this: http://www.springframework.org/schema/beans"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:util="http://www.springframework.org/schema/util";

Re: Affinity Key column to be always part of the Primary Key

Based this latest description, simply not specifying an affinity key here would be sufficient. But presumably you were specifying the affinity key to cause co-location. The reason a lookup on the K of the KV pair is fast is because it can hash to a node. If the affinity key was not included
