FAQ
How do i add new product (currency pair)?
curl -X PUT -H "Content-Type:application/json" http://127.0.0.1/api/admin/products -d '{"baseCurrency":"BTC","quoteCurrency":"USDT"}'
Does the project include blockchain wallets?
No, you need to implement it yourself, and then connect to gitbiex.
For example, after users recharge/withdraw, send DepositCommand/WithdrawalCommand to the matching engine
Can I use this project for production?
Probably not. Some customers I know use this project in production, but they all have professional technicians.
If you want to use it in production, you need professional technicians to help you. Like me .
How can I monitor the performance of the matching engine?
Some prometheus metrics for measuring performance have been built into the project.
You can visit http://127.0.0.1:7002/actuator/prometheus see.You can use Prometheus and grafana to monitor.
The metrics are as follows:
- gbe_matching_engine_command_processed_total : The number of commands processed by the matching engine. The greater the value change, the faster the processing.
- gbe_matching_engine_modified_object_created_total : This value represents the number of objects that have modified,Wait to save to database.
- gbe_matching_engine_modified_object_saved_total : The number of modified objects that have been saved. If the difference between this value and _gbe_matching_engine_modified_object_createdtotal is too large, it means that saving to disk is too slow.
- gbe_matching_engine_snapshot_taker_modified_objects_queue_size : Objects that have not been written to the snapshot. This value reflects the performance of the snapshot thread.
