Hi Team,

I have written this code , which basically stores three numbers in the DB (1,8,10) and then tries to print them one by one.
I call dbi.first() to get the first key, however the code below does not returns first key, instead creates an infinite loop.

Please assist whats wrong?

const MDBX = require("node-mdbx");
const db = new MDBX({
    path: '/tmp/test_db',
    maxDbs: 5,
    syncMode: 'safeNoSync',
    readOnly: false,
    pageSize: 65536,
    keyMode: 'string',
    valueMode: 'buffer',
  });
  
  const result = db.transact(txn => {
    const dbi = txn.getDbi('main');

    { 
        //insert
        let buff = Buffer.alloc(8);
        buff.writeDoubleBE(10.2);
        dbi.put(buff, '10');
     }
    
   {
      //insert
      let buff = Buffer.alloc(8);
      buff.writeDoubleBE(1);
      dbi.put(buff, '1');
   }

   {
    //insert
    let buff = Buffer.alloc(8);
    buff.writeDoubleBE(8);
    dbi.put(buff, '8');
    }
  
   {
    //reading first key
    let key = dbi.first();
     
    let value = dbi.get(key);
    console.log(String(value));
    while(key){
        key=dbi.next(key);
        if(key){
            let b = Buffer.alloc(8,key);
            console.log("found key:",b.readDoubleBE(),"found value:", String(dbi.get(key)));
        }
    }
   }
  });

Do I understand it right, that this library doesn't support MDBX DupSort feature and DB flags in general (MDBX_DUPFIXED)?

Hi team,

What is the maximum number of dbs one can create on mdbx ?

How to generate mdbx.c ? I trying update mdbx.c to latest , but not found mdbx.c

terminate called after throwing an instance of 'DbException'
    what():  MDBX_VERSION_MISMATCH: DB version mismatch libmdbx

Currently supported version is 0.10.x
