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) pybreakerrrEr)selfcircuit_breakers r7default_circuit_breakerz&DatabaseConfig.default_circuit_breakerYs##22ARARS&77r6)r/r0r1__doc__r>float__annotations__rdictrArBrstrrCr rDrrrErFrLr5r6r7r=r=7ss0FE5M45"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_probes_delay: Delay between health check attempts. health_check_policy: Policy for determining database health based on health checks. 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_probes_delayhealth_check_policyfailover_strategyfailover_attemptsfailover_delayauto_fallback_intervalr?event_dispatcherinitial_health_check_policyr8c t}|jD]l}tdt|jd<d|jvrt d|jd<|j r2|jj |j fi|j}n}|jrU|jjtdt|jj|j}n|jd i|j}|j|jn |j}|jt|||j|j|jo|S) Nr)r\r[retrymaint_notifications_configF)enabled)connection_pool)clientrDr>rFr5)rrTr(rrArrBrUrC set_retryrDrLaddrr>rF)rJ databasesdatabase_configrrrDs r7ruzMultiDbConfig.databasessz N #44) O6;9;6O ) )' 2 ,?3P3PP,U; --.JK''3**33#,,0?0M0M!**))33!Y[9**44$3$=$=5+**K_-J-JK#**2 779$,,  MM!#*11%4%E%E   && C) Vr6c\t|j|j|jgS)N)r_r`failure_detection_window)rr_r`rarJs r7default_failure_detectorsz'MultiDbConfig.default_failure_detectorss/ "!%!6!6'+'B'B)-)G)G   r6ctgSr:)r'rys r7default_health_checksz#MultiDbConfig.default_health_checkss    r6ctSr:)rrys r7default_failover_strategyz'MultiDbConfig.default_failover_strategys *,,r6)9r/r0r1rMrr=rOr rUrr r r(r r]r^rr rr_intrr`rNrrarbr%r"rcr$rdr!rer#rfr&rgrrrhrriDEFAULT_AUTO_FALLBACK_INTERVALrjrr;rkrr+r2rlrrurzr|r~r5r6r7rSrS^s\(T>**5:L$uUL012: ,!x_ 56=4c4$BEB'HuH15M8D-.5#@5@::'AuA/J,J48x 0186s62NE2$BEB1602.7I6V6V!3V.9.` 4+@  tK'8 -+;-r6rS): dataclassesrrenumrtypingrrrr rIredisr r r redis.backoffr rredis.data_structurer redis.eventrrredis.maint_notificationsrredis.multidb.circuitrrrredis.multidb.databaserrredis.multidb.failoverrrrrredis.multidb.failure_detectorrrrrr redis.multidb.healthcheckr!r"r#r$r%r&r' redis.retryr(rr+r;r=rSr5r6r7rs(..55A-A> 7 !$$$ ": #8#8 #8L A-A- A-r6
