-----------------------------------
Attachment: alterTableTest1.java
> Altering the table causes the KV API to break
> ---------------------------------------------
>
> Key: IGNITE-21296
> URL: https://issues.apache.org/jira/browse/IGNITE-21296
> Project: Ignite
> Issue Type: Bug
> Reporter: Ivan Gagarkin
> Priority: Critical
> Labels: ignite-3
> Attachments: alterTableTest1.java
>
>
>
> *Steps to Reproduce:*
> # Create a table using the command: {{{}CREATE TABLE TEST (id INT PRIMARY
> KEY, country VARCHAR){}}}.
> # Create a POJO with corresponding fields to the table.
> # Create a Key-Value (KV) view: {{{}KeyValueView<Integer, Country>
> countryValueView = table.keyValueView(Mapper.of(Integer.class),
> Mapper.of(Country.class));{}}}.
> # Insert some data into the table.
> # Alter the table by adding a new column: {{{}ALTER TABLE TEST ADD COLUMN
> city VARCHAR{}}}.
> # Create a new POJO to accommodate the added column.
> # Create a new KV view: {{{}KeyValueView<Integer, CountryCity>
> countryCityKeyValueView =
> CLUSTER.node(0).tables().table(TABLE_NAME).keyValueView(Mapper.of(Integer.class),
> Mapper.of(CountryCity.class));{}}}.
> # Attempt to remove data from the table using the first KV view:
> {{{}assertTrue(countryValueView.remove(null, 0, valuePojo));{}}}. This fails
> with the error "No mapped object field found for column 'CITY'".
> # Try to remove data using the second KV view:
> {{{}assertTrue(countryCityKeyValueView.remove(null, 0, new
> CountryCity(valuePojo.country(), null)));{}}}. This returns {{{}false{}}}.
> *Expected Behavior:*
> ** It should be possible to remove values using either of the KV views after
> altering the table structure.
> *Actual Behavior:*
> ** Unable to remove values using the first KV view due to the lack of a
> 'city' column in the original POJO.
> ** Unable to remove values using the second KV view as the {{equals}} method
> does not function as expected.
