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_urlr9cXtj|j}t|S)N) reset_timeout) pybreakerr$rFr%)selfcircuit_breakers r8default_circuit_breakerz&DatabaseConfig.default_circuit_breaker\s##22ARARS&77r7)r0r1r2__doc__r?float__annotations__rdictrBrCrstrrDr rEr$r#rFrGrMr6r7r8r>r>:ss0FE5M45"Hhsm"*.Ix'.(,GXn %,.L%.&*hsm*88r7r>ceZdZUdZeeed<eZe e ee fed<e e dddZe ed <d Zeeeed <eZeed <eZeed <eZeed<d Zeeeed<eZeed<eZeed<e Z!eed<e"Z#eed<e$Z%e&ed<d Z'ee(ed<e)Z*eed<e+Z,eed<e-Z.eed<e/e0Z1e2ed<e3jhZ5e3ed<de6fdZ7deefdZ8deefdZ9de(fd Z:y )! 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. health_check_timeout: Timeout for the full health check operation (including all probes). 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_delayhealth_check_timeouthealth_check_policyfailover_strategyfailover_attemptsfailover_delayauto_fallback_intervalr@event_dispatcherinitial_health_check_policyr9c 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)clientrEr?rGr6)r rUrBupdaterrrCrVrD set_retryrErMaddr r?rG)rK databasesdatabase_configrrrEs r8rvzMultiDbConfig.databasessT N #44O  ) ) 0 0%9;?@ ''3**33#,,0?0M0M!**))33!Y[9**44$3$=$=5+**K_-J-JK#**2 779$,,  MM!#*11%4%E%E   && 5 5Hr7cntt|j|j|jgS)N)r`rafailure_detection_window)rr)r`rarbrKs r8default_failure_detectorsz'MultiDbConfig.default_failure_detectorss7 '&%)%:%:+/+F+F-1-K-K   r7c\t|j|j|jgS)N)rerfrg)rrerfrgrzs r8default_health_checksz#MultiDbConfig.default_health_checkss/ $($<$<#'#:#:%)%>%>   r7ctSr;)rrzs r8default_failover_strategyz'MultiDbConfig.default_failover_strategys *,,r7);r0r1r2rNrr>rPr rVrr r rrr^r_rrr(r`intr&rarOr'rbrcrrrdrrerrfrrgrrhrrirrrjrrkDEFAULT_AUTO_FALLBACK_INTERVALrlrr<rmr"r,r3rnrrvr{r}rr6r7r8rTrTasj)V>**5:L$uUL012: ,!%>/J,J9=x 56=6s62NE2$BEB1602.7I6V6V!3V'9'R  40D+E   tK'8 -+@-r7rT); dataclassesrrenumrtypingrrrr rJ redis.asyncior r r redis.asyncio.multidb.databaser rredis.asyncio.multidb.failoverrrrr&redis.asyncio.multidb.failure_detectorrr!redis.asyncio.multidb.healthcheckrrrrrrrrredis.asyncio.retryr redis.backoffrrredis.data_structurer redis.eventr!r"redis.multidb.circuitr#r$r%redis.multidb.failure_detectorr&r'r(r)rr,r<r>rTr6r7r8rs(..==>    &A-A "%$$ ": #8#8 #8L B-B- B-r7
