This class is used to store configuration settings for a database connection, including client options, connection sourcing details, circuit breaker settings, and cluster-specific properties. It provides a structure for defining these attributes and allows for the creation of customized configurations for various database setups. Attributes: weight (float): Weight of the database to define the active one. client_kwargs (dict): Additional parameters for the database client connection. from_url (Optional[str]): Redis URL way of connecting to the database. from_pool (Optional[ConnectionPool]): A pre-configured connection pool to use. circuit (Optional[CircuitBreaker]): Custom circuit breaker implementation. grace_period (float): Grace period after which we need to check if the circuit could be closed again. health_check_url (Optional[str]): URL for health checks. Cluster FQDN is typically used on public Redis Enterprise endpoints. Methods: default_circuit_breaker: Generates and returns a default CircuitBreaker instance adapted for use. g?weightdefault_factory client_kwargsNfrom_url from_poolcircuit grace_periodhealth_check_urlr8cXtj|j}t|S)N) reset_timeout) pybreakerr#rEr$)selfcircuit_breakers r7default_circuit_breakerz&DatabaseConfig.default_circuit_breaker[s##22ARARS&77r6)r/r0r1__doc__r>float__annotations__rdictrArBrstrrCr rDr#r"rErFrLr5r6r7r=r=9ss0FE5M45"Hhsm"*.Ix'.(,GXn %,.L%.&*hsm*88r6r=ceZdZUdZeeed<eZe e ee fed<e e dddZe ed <d Zeeeed <eZeed <eZeed <eZeed<d Zeeeed<eZeed<eZeed<e Z!eed<e"Z#e$ed<d Z%ee&ed<e'Z(eed<e)Z*eed<e+Z,eed<e-e.Z/e0ed<e1jdZ3e1ed<de4fdZ5deefdZ6deefdZ7de&fdZ8y ) MultiDbConfiga. Configuration class for managing multiple database connections in a resilient and fail-safe manner. Attributes: databases_config: A list of database configurations. client_class: The client class used to manage database connections. command_retry: Retry strategy for executing database commands. failure_detectors: Optional list of additional failure detectors for monitoring database failures. min_num_failures: Minimal count of failures required for failover failure_rate_threshold: Percentage of failures required for failover failures_detection_window: Time interval for tracking database failures. health_checks: Optional list of additional health checks performed on databases. health_check_interval: Time interval for executing health checks. health_check_probes: Number of attempts to evaluate the health of a database. health_check_delay: Delay between health check attempts. failover_strategy: Optional strategy for handling database failover scenarios. failover_attempts: Number of retries allowed for failover operations. failover_delay: Delay between failover attempts. auto_fallback_interval: Time interval to trigger automatic fallback. event_dispatcher: Interface for dispatching events related to database operations. initial_health_check_policy: Defines the policy used to determine whether the databases setup is healthy during the initial health check. Methods: databases: Retrieves a collection of database clients managed by weighted configurations. Initializes database clients based on the provided configuration and removes redundant retry objects for lower-level clients to rely on global retry logic. default_failure_detectors: Returns the default list of failure detectors used to monitor database failures. default_health_checks: Returns the default list of health checks used to monitor database health with specific retry and backoff strategies. default_failover_strategy: Provides the default failover strategy used for handling failover scenarios with defined retry and backoff configurations. databases_config client_class )basecap)backoffretries command_retryNfailure_detectorsmin_num_failuresfailure_rate_thresholdfailures_detection_window health_checkshealth_check_intervalhealth_check_probeshealth_check_delayhealth_check_policyfailover_strategyfailover_attemptsfailover_delayauto_fallback_intervalr?event_dispatcherinitial_health_check_policyr8c t}|jD]S}|jjdt dt i|j r2|jj |j fi|j}n}|jrU|jjt dt |jj|j}n|jdi|j}|j|jn |j}|jt|||j|j|jV|S)Nretryr)r\r[)connection_pool)clientrDr>rFr5)rrTrAupdaterrrBrUrC set_retryrDrLaddr r>rF)rJ databasesdatabase_configrprDs r7rtzMultiDbConfig.databasessY N #44" O  ) ) 0 0%9;?@ ''3**33#,,0?0M0M!**))33!Y[9**44$3$=$=5+**K_-J-JK#**2 779$,,  MM!#*11%4%E%E   && 5" Hr6cntt|j|j|jgS)N)r_r`failure_detection_window)rr(r_r`rarJs r7default_failure_detectorsz'MultiDbConfig.default_failure_detectorss7 '&%)%:%:+/+F+F-1-K-K   r6ctgSr:)rrxs r7default_health_checksz#MultiDbConfig.default_health_checkss    r6ctSr:)rrxs r7default_failover_strategyz'MultiDbConfig.default_failover_strategys *,,r6)9r/r0r1rMrr=rOr rUrr r rrr]r^rrr'r_intr%r`rNr&rarbrrrcrrdrrerrfrrgrrrhrriDEFAULT_AUTO_FALLBACK_INTERVALrjrr;rkr!r+r2rlrrtryr{r}r5r6r7rSrS`s_'R>**5:L$uUL012: ,!rs(..==> &A-A "%  ": #8#8 #8L {-{- {-r6
