Assignee: Vladimir Steshin
> Document same SQL table value_type for CDC.
> -------------------------------------------
>
> Key: IGNITE-18223
> URL: https://issues.apache.org/jira/browse/IGNITE-18223
> Project: Ignite
> Issue Type: Improvement
> Components: documentation
> Reporter: Vladimir Steshin
> Assignee: Vladimir Steshin
> Priority: Major
> Labels: ise
>
> To replicate data through CDC, SQL/CDC documentation should mention that both
> SQL tables on the source and destination nodes have to have the same
> 'value_type' like:
> {code:sql}
> CREATE TABLE Person (id int primary key, varchar name) with
> cache_name='Person', value_type='SQL_PERSON_TABLE_TYPE'
> {code}
> Otherwise, successfully replicated data is not seen by SQL queries on the
> receiver node. This happens because the recipient node has its own generated
> binary type name for its related table. Replication of schema or any settings
> aren't supported yet.
> Binary type name is randomly generated for SQL table because we do not delete
> binary types at all. Type name based only on table name/schema can breake:
> {code:sql}
> sql("create table tst(id int)");
> sql("insert into tst values (1)");
> sql("drop table tst");
> sql("create table tst(id varchar)");
> sql("insert into tst values ('1')");
> {code}
