Re: AffinityKey - best practice

Hi Raj, Affinity collocation is an essential part of distributed caches and databases like Ignite that allows to store related data on the same cluster machine and, thus, making performance of particular operations much faster. These resources will help you to grasp the idea and usefulness of

query on BinaryObject index and table

Hi, I have requirement that my schema is not fixed , so I have to use the BinaryObject approach instead of fixed POJO I am relying on OOTB file system persistence mechanism My questions are: - How can I specify the indexes on BinaryObject? - If I have to use sql query for retrieving objects ,
