python – A copy in postgres in parallel gets the duplicate records

We have a pyspark script that can read the data from the hive table and write this data in postgres, the main part is pasted below, most of the time it works well, but sometimes the duplicate records are duplicated in the table postgres target. the reason caused the duplicates?

def write_data (partition):
output = StringIO ()
writer = csv.writer (output, delimiter =  t & # 39;  t)
writer.writerows (partition)

output.seek (0)

conn = psycopg2.connect (connection_url)
cur = conn.cursor ()
query = "COPY {} FROM STDIN WITH (CSV FORMAT, DELIMITER E") ". format (table_name)
cur.copy_expert (request, exit)
conn.commit ()
cur.close ()
conn.close ()

df = read_hive_table (table_name)
df.foreachPartition (write_data)

Why on a Sony SLT-A65V with dynamic range optimization, I get three almost duplicate photos. Now what?

I turned on DRO and this gives me 3 slightly different pictures of the same thing.

Now what?

  1. Decide manually which is the best?
  2. Recombine them in one single best photo? How?
  3. Something else

Final goal

To have 1 copy of each image that benefits from DRO.

signature – How does Bitcoin ensure that no one can duplicate a transaction?

However, what prevents someone, for example the recipient of the original transaction, from simply sending the same exact transaction with the same data and signature?

Bitcoin does not have the concept of account balance but is working on the concept of unspent transaction exits (UTXO). Each output of a transaction (except OP_RETURN some) lead to the creation of a separate UTXO. When you create transactions in Bitcoin, you use these UTXOs in their entirety and create separate UTXOs. This is done by referencing the exit point (txid and not) from which you earn these UTXOs. For example, if you control 2 UTXOs (1 BTC and 0.5 BTC) and you want to send your friend 1.25 BTC, you will have to consume your two UTXOs and send you the remaining change of 0.25 BTC. neglected tx). So, if the recipient of a transaction output tries to broadcast the same transaction again, the Bitcoin nodes when checking the transaction would find that these utxos do not exist and that, therefore, the transaction is not valid.

When the full nodes begin to synchronize from the Genesis block, they begin to create the database of all these UTXOs. Each transaction involves the removal of used UTXOs and the addition of new ones. These databases are stores in state of the chain directory and cached aggressively in memory.

This question was inspired by an answer to this question. Suppose the players are trying to protect their little village from a huge monster, Godzilla in this case. Obviously, they would have the sting if they murdered Godzilla with their sword or they would band together to sing a moving song to convince the huge beast to look for a meal elsewhere.
However, would they get Xp to lure Mothra into Godzilla's path and make the two titans run off (thus preventing the destruction of their village)?

The question that inspired this was specific to the 5th edition, so I would prefer the answers from this rule set, though if one of the older systems has an interesting point of view, I'm happy to read.

For search engines, mainly Google, which is better:

or:
