--------------------------------------
Summary: 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
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.
