# How to prevent current cron job submiting a transaction with same sequence number with the transaction submitted by the previous cron job while it is not finished yet.
The sender account's current sequence number is saved in `./data/
.txt` locally.
It is used to prevent a cron job submit a trnasaction onto the chain with the same sequence number(locally and on the chain) and will be failed.
If the sequence number are equaly, the current job will abort immediately, and wait for the next cron job.
# How to use
1. Normally, we can batch transfer 5 new records each time with 1 sender.
```
node index.js --network=barnard --senderIndex=0 --count=5
```
The output is:
```

```
2. In emergency conditions(eg. thousands of new records were added on the promotion day), we can batch handle them in parrael using multi senders.
```
node index.js --network=barnard --senderIndex=0 --count=50
node index.js --network=barnard --senderIndex=1 --count=50
...
```
