[~tledkov-gridgain] please review amended fix.
> Warning if no table for BinaryObject
> ------------------------------------
>
> Key: IGNITE-6528
> URL: https://issues.apache.org/jira/browse/IGNITE-6528
> Project: Ignite
> Issue Type: Improvement
> Components: binary, cache, sql
> Reporter: Mikhail Cherkasov
> Assignee: Ilya Kasnacheev
> Priority: Major
>
> I've seen several times that due wrong cache configuration people can't find
> data in cache and blame Ignite that it's buggy and doesn't work.
> And it's very difficult to find an error in the code, especially if you don't
> have reach experience with Ignite.
> The problem is that we don't have strong typing when defining QueryEntriy and
> a user can use an arbitrary string id to
> define a type, but he should use the same string id to obtain binary object
> builder, however, people sometimes confusing this.
> So the user can define QueryEntity with value type:
> queryEntity.setValueType("MyCoolName") and
> later put to cache the following binary object:
> ignite.binary.toBinary(value), but this object won't be indexed, because
> ignite.binary.toBinary uses class name as string id while indexing expects to
> find "MyCoolName" as id.
> The example is simple and the error is obvious when you see this two lines
> close to each other, however, in real life, cache definition and data
> ingestion are separated by tons of code.
> We can save a lot of man-hours for our users if Ignite will print a warning
> If a cache has a configured QE and user puts BinaryObject with typeName which
> doesn't correspond to any QE.
> The warning should be printed only once, something like:
> [WARN] No table is found for %typeName% binary object.
