TrafficPurchasedManager
Companion object TrafficPurchasedManager
class TrafficPurchasedManager extends NamedLogging with FlagCloseable with HasCloseContext
Manages traffic purchased entries for sequencer members. This borrows concepts from topology management, in a simplified way. There is no "change delay", which has the direct consequence that traffic purchased entry updates need to be processed sequentially before subsequent messages read in the BlockUpdateGenerator can be processed. We also only here keep track of the latest *few* balance updates for each member in memory. Older traffic states will have to be fetched from the database. Traffic purchased entries can be automatically pruned from the cache AND the store according to pruningRetentionWindow.

Add a new traffic purchased entry to the store and the cache. TrafficPurchased with a serial less or equal to the most recent one will be ignored. Together with tick, this method expects to be called sequentially with balances in increasing order of sequencingTimestamp. This method MUST NOT be called concurrently.

Return the traffic purchased entry valid at the given timestamp for the given member.
Return the traffic purchased entry valid at the given timestamp for the given member. TrafficPurchased are cached in this class, according to the cache size defined in trafficConfig. Requesting balances for timestamps outside of the cache will trigger a lookup in the database. The balances in this class are updated after they've been processed and validated by the sequencer client, however they can be queried on the sequencer read path. To avoid providing incorrect balance values while balance updates are "in-flight" (as in being processed by the sequencer client), the parameter lastSeen0 can be provided. This parameter indicates to the function the youngest timestamp for which the caller thinks a balance update might have been sequenced. This allows this function to compare this timestamp with the internal state, and if necessary, wait for the potential update before providing the balance. Note that if requesting a traffic purchased entry at a timestamp that has already been pruned, the function will return an error.
- member
member to request the traffic purchased entry for
- desired
the timestamp for which the balance is requested
- lastSeenO
the youngest timestamp for which the caller thinks a balance update might have been sequenced
- warnIfApproximate
if no lastSeen0 is provided, and the desired timestamp is more recent than the last update, a warning will be logged if this is true
- returns
the traffic purchased entry valid at the given timestamp for the given member, or empty if no balance exists for that member
