> Descriptions on [https://apacheignite-sql.readme.io/docs/schema-and-indexes] are not
> After reading this page and [https://apacheignite-sql.readme.io/docs/insert], one would
likely still unable to write working INSERT because there won't be primary key in it.
> Their only chance is to spot _key reference in infoblock, or infer usability of setKeyFields()
with single key type. Both are unlikely, leading to questions such as [https://stackoverflow.com/questions/48460214/how-do-i-read-data-from-ignite-kv-storage-using-jdbc]
see {{Key is missing from query}}
> Such problems are hard to debug. They can be avoided if all examples of QueryEntities
in docs will contain setKeyFields, and INSERT docs page will refer to _key field.
