This class does not perform any IO. It simply updates internal state given API responses (MetadataResponse, GroupCoordinatorResponse). Keyword Arguments: retry_backoff_ms (int): Milliseconds to backoff when retrying on errors. Default: 100. metadata_max_age_ms (int): The period of time in milliseconds after which we force a refresh of metadata even if we haven't seen any partition leadership changes to proactively discover any new brokers or partitions. Default: 300000 bootstrap_servers: 'host[:port]' string (or list of 'host[:port]' strings) that the client should contact to bootstrap initial cluster metadata. This does not have to be the full node list. It just needs to have at least one broker that will respond to a Metadata API Request. Default port is 9092. If no servers are specified, will default to localhost:9092. di)retry_backoff_msmetadata_max_age_msbootstrap_serversc B0Ul0Ul[R"[5Ul0UlSUlSUlSUl SUl [ 5Ul [R"5UlSUl[ 5Ul[ 5UlSUl[&R&"UR(5UlUR*HnX!;dM XUR*U'M UR-5Ul0Ul0Ul0Ulg)NrTF)_brokers _partitions collections defaultdictset_broker_partitions_groups_last_refresh_ms_last_successful_refresh_ms _need_update_future _listeners threadingLock_lockneed_all_topic_metadataunauthorized_topicsinternal_topics controllercopyDEFAULT_CONFIGconfig_generate_bootstrap_brokers_bootstrap_brokers_coordinator_brokers _coordinators_coordinator_by_key)selfconfigskeys UC:\Suresh\moveshuttle\MDcreated\moveengine\venv\Lib\site-packages\aiokafka/cluster.py__init__ClusterMetadata.__init__,s "-"9"9#"> !+,(  %^^% ',$#&5 "uii 3 34 ;;C~#*< C #'"B"B"D$&!#% c[URS5n0n[U5HunupEnSU3n[XtUS5X''M U$)Nrz bootstrap-)rr' enumerater)r-bootstrap_hostsbrokersihostport_node_ids r0r(+ClusterMetadata._generate_bootstrap_brokersGsW' 4G(HI"+O"< AA"1#&G-gT4HG #=r3cXR;$N)r)r-r<s r0 is_bootstrapClusterMetadata.is_bootstrapQs1111r3c[URR55=(d# [URR55$)z@Get all BrokerMetadata Returns: set: {BrokerMetadata, ...} )rrvaluesr)r-s r0r7ClusterMetadata.brokersTs5 4=='')*Sc$2I2I2P2P2R.SSr3cURRU5=(d= URRU5=(d URRU5$)zGet BrokerMetadata Arguments: broker_id (int): node_id for a broker to check Returns: BrokerMetadata or None if not found )rgetr)r*r- broker_ids r0broker_metadataClusterMetadata.broker_metadata\sM MM  i ( 8&&**95 8((,,Y7 r3topicreturncnXR;ag[URUR55$)zReturn set of all partitions for topic (whether available or not) Arguments: topic (str): topic to check for partitions Returns: set: {partition (int), ...} N)rrkeys)r-rMs r0partitions_for_topic$ClusterMetadata.partitions_for_topicks2 (( (4##E*//122r3cXR;agURUR5VVs1sHup#URS:wdMUiM snn$s snnf)zReturn set of partitions with known leaders Arguments: topic (str): topic to check for partitions Returns: set: {partition (int), ...} None if topic not found.
