Queue Parameters

TODO Explain Queue module. The queue holds incoming transactions. From time to time, Sumeragi fetches them in order to create a block.

queue.future_threshold

• Type: String or Number, Duration
• Default: 1 second

The threshold to determine if a transaction has been tampered with to have a future timestamp.

TODO: explain that timestamp is the value specified in TransactionPayload's creation_time_ms field.

Example:

[queue]
future_threshold = "1s"

queue.max_transactions_in_queue

• Type: u32
• Default: $2^{16} = 65\ 536$

The upper limit of the number of transactions waiting in the queue.

Example:

[queue]
max_transactions_in_queue = 65_536

queue.max_transactions_in_queue_per_user

• Type: u32
• Default: $2^{16} = 65\ 536$

The upper limit of the number of transactions waiting in the queue for a single user. Use this option to apply throttling.

Example:

[queue]
max_transactions_in_queue_per_user = 65_536

queue.transaction_time_to_live

• Type: String or Number, Duration
• Default: 24 hours

The transaction will be dropped after this time if it is still in the queue.

TODO: there is also TransactionPayload's time_to_live parameter. We should probably say here that configuration parameter has higher priority. Name it queue.max_transaction_time_to_live?

Example:

[queue]
transaction_time_to_live = "24h"
