Large Table

C++
Java
Here is a sample program which does most of the operations to help you understand the APIs and their usage.
bool flag = true;
DBParam dp;
dp.setTransactionType(DB_TRANSACTION_NONE);
BangDBDatabase * bdb = new BangDBDatabase("mydb", & dp);
if (!bdb) {
    printf("db could not be created, quitting\n");
    //return or handle error
}
// db_param sets the db environment, see the section to know more about it
// create a large table
TableEnv te;
te.setTableType(LARGE_TABLE);
// large table must have composite primary key, else db will throw error
te.setKeyType(COMPOSITE_KEY);
te.setKeySize(64); // set key size keeping ~32 bytes for system to add/consume
BangDBTable * large_tbl = bdb -> getTable("my_large_tbl", & te, OPENCREATE);
if (!large_tbl) {
    printf("we could not create the table my_large_tbl\n");
    flag = false;
    // handle error
}
// let's load large file
const char * file_path = "libbangdb.so.2.0";
const char * fkey = "bangdb_2_0_binary";
FDT fk;
set_fat( & fk, fkey);
if (large_tbl -> putFile( & fk, file_path, INSERT_UNIQUE) < 0) {
    printf("error in putting large file\n");
    flag = false;
    // handle error
}
const char * file_name = "linbangdb.so.2.0_new_name";
const char * download_fpath = "/tmp";
if (large_tbl -> getFile( & fk, file_name, download_fpath) < 0) {
    printf("get file error\n");
    flag = false;
    // handle error
}
int nslices = large_tbl -> countSliceLarge_data( & fk);
printf("num of slices for the file = %d\n", nslices);
const char * finfo = large_tbl -> listLargeDataKeys(fkey);
printf("the file info = %s\n", finfo);
delete[] finfo;
delete large_tbl;
bdb -> closeDatabase(DEFAULT);
delete bdb;
