Summary: Java thin client: Configure cache paritions count
Key: IGNITE-27938
URL: https://issues.apache.org/jira/browse/IGNITE-27938
Project: Ignite
Issue Type: Improvement
Components: thin client
Reporter: Aleksey Plekhanov
Assignee: Aleksey Plekhanov
It's a common request from users to have an ability to configure cache
partitions count through thin clients. The problem is: partitions count it's a
parameter of affinity function, and affinity function is a java class.
Technically, we have all posibilities to pass configured affinity function from
clients to server, if affinity function/backup filter classes already on
servers (in 99.99% cases built-in rendevois affinity function is used, without
filters or with one of built-in filters), but this approach have some cons, for
example it's applicable only for java thin client.
It's proposed to include just one parameter to ClientCacheConfiguration:
partitions count and create default affinity function on server side with this
partitions count. It will reduce complexity for users and will solve the
problem.
Currently, we also can provide custom partitions count and custom affinity
functions by preconfiguring cache templates on server-side and using these
templates on client-side.
