type PluginConfig

type PluginConfig struct {
	// CacheExpiration is the duration of time a cached key is available. Use
	// this value to balance memory usage and RPC calls. A new set of keys is
	// generated with every block so a good setting might come from block time
	// times number of blocks of history to support not replaying reports.
	CacheExpiration Duration `json:"cacheExpiration"`
	// CacheEvictionInterval is a parameter for how often the cache attempts to
	// evict expired keys. This value should be short enough to ensure key
	// eviction doesn't block for too long, and long enough that it doesn't
	// cause frequent blocking.
	CacheEvictionInterval Duration `json:"cacheEvictionInterval"`
	// MaxServiceWorkers is the total number of go-routines allowed to make RPC
	// simultaneous calls on behalf of the sampling operation. This parameter
	// is 10x the number of available CPUs by default. The RPC calls are memory
	// heavy as opposed to CPU heavy as most of the work involves waiting on
	// network responses.
	MaxServiceWorkers int `json:"maxServiceWorkers"`
	// ServiceQueueLength is the buffer size for the RPC service queue. Fewer
	// workers or slower RPC responses will cause this queue to build up.
	// Adding new items to the queue will block if the queue becomes full.
	ServiceQueueLength int `json:"serviceQueueLength"`
