----------------------------------------
Fix Version/s: 3.2
(was: 3.1)
> Support collocation based on multiple fields
> --------------------------------------------
>
> Key: IGNITE-13671
> URL: https://issues.apache.org/jira/browse/IGNITE-13671
> Project: Ignite
> Issue Type: Improvement
> Reporter: Valentin Kulichenko
> Priority: Major
> Labels: ignite-3
> Fix For: 3.2
>
>
> In Ignite 2.x there are two ways to configure collocation: @AffinityKeyMapped
> annotation and CacheKeyConfiguration bean. Both allow specifying *only one
> field* to be used for collocation.
> Let's say there is a key class that looks like this:
> {code:java}
> class MyCacheKey {
> int a;
> int b;
> int c;
> }{code}
> In this case, there is no way to collocate the data based on a pair of fields
> (e.g. a and b).
> In 3.0, we should have an API that would allow to specify two or more fields
> to be used for collocation.
