> [ClientTableCommon#writeSchema|https://github.com/apache/ignite-3/blob/317aca963ed9c87e14dd6eebd3284408fb550c8c/modules/client-handler/src/main/java/org/apache/ignite/client/handler/requests/table/ClientTableCommon.java#L75]
> does not preserve the order of colocation columns. It assumes that key
> column order is the same as colocation column order, which is not always true.
> * Fix *writeSchema* somehow to specify the order of colocation columns (maybe
> send their indices as a separate array)
> * Fix clients (.NET, Java, C++) accordingly
