Cache ¶

The cache subpackage provides common caching infrastructure.

class CacheDatabaseAdapter ( TraderId trader_id , UUID4 instance_id , Serializer serializer , config: CacheConfig | None = None ) ¶

Bases: CacheDatabaseFacade

Provides a generic cache database adapter.

Parameters :

trader_id ( TraderId ) – The trader ID for the adapter.
instance_id ( UUID4 ) – The instance ID for the adapter.
serializer ( Serializer ) – The serializer for database operations.
config ( CacheConfig , optional ) – The configuration for the instance.

Raises :

TypeError – If config is not of type CacheConfig .

Warning

Redis can only accurately store int64 types to 17 digits of precision. Therefore nanosecond timestamp int64’s with 19 digits will lose 2 digits of precision when persisted. One way to solve this is to ensure the serializer converts timestamp int64’s to strings on the way into Redis, and converts timestamp strings back to int64’s on the way out. One way to achieve this is to set the timestamps_as_str flag to true for the MsgSpecSerializer , as per the default implementations for both TradingNode and BacktestEngine .
