Hi everyone,
In official document, there are some code about Partition-aware data
loading.
private void loadPartition(Connection conn, int part,
IgniteBiInClosure<Long, Person> clo) {
try (PreparedStatement st = conn.prepareStatement("select * from PERSONS
where partId=?")) {
st.setInt(1, part);
try (ResultSet rs = st.executeQuery()) {
while (rs.next()) {
Person person = new Person(rs.getLong(1), rs.getString(2),
rs.getString(3));
clo.apply(person.getId(), person);
}
}
}
catch (SQLException e) {
throw new CacheLoaderException("Failed to load values from cache store.",
e);
}
} I have a question in real scenario in the previous bold code: My table
like Person has 100 columns, so I will list so many colmuns, it is not very
efficient. But, in the default implemention of cache.loadCache(), there are
good code for mapping the DB table to cache object. Can I reuse these code
through some API? Thanks your reply.
Bob
