### Question:
GenerateTableFetch extends AbstractDatabaseFetchProcessor { private Integer getColumnType(String tableName, String colName, DatabaseAdapter adapter) { final String fullyQualifiedStateKey = getStateKey(tableName, colName, adapter); Integer type = columnTypeMap.get(fullyQualifiedStateKey); if (type == null && !isDynamicTableName) { type = columnTypeMap.get(getStateKey(null, colName, adapter)); } return type; } GenerateTableFetch(); @Override Set<Relationship> getRelationships(); @Override @OnScheduled void setup(final ProcessContext context); @OnStopped void stop(); @Override void onTrigger(final ProcessContext context, final ProcessSessionFactory sessionFactory); static final PropertyDescriptor PARTITION_SIZE; static final Relationship REL_FAILURE; }### Answer:
