    • bootstrapServers

      public T bootstrapServers(List<String> value)
      Description copied from interface: ConsumerConfigFields

      bootstrap.servers

      A list of host/port pairs to use for establishing the initial connection to the Kafka cluster.
      The client will make use of all servers irrespective of which servers are specified here for bootstrapping—this list only impacts the initial hosts used to discover the full set of servers.
      This list should be in the form host1:port1,host2:port2,....
      Since these servers are just used for the initial connection to discover the full cluster membership (which may change dynamically), this list need not contain the full set of servers (you may want more than one, though, in case a server is down).

      Default: ""

    • clientDnsLookup

      public T clientDnsLookup(String value)
      Description copied from interface: ConsumerConfigFields

      client.dns.lookup

      Controls how the client uses DNS lookups.
      If set to use_all_dns_ips, connect to each returned IP address in sequence until a successful connection is established.
      After a disconnection, the next IP is used.
      Once all IPs have been used once, the client resolves the IP(s) from the hostname again (both the JVM and the OS cache DNS name lookups, however).
      If set to resolve_canonical_bootstrap_servers_only, resolve each bootstrap address into a list of canonical names.
      After the bootstrap phase, this behaves the same as use_all_dns_ips.

      Default: use_all_dns_ips

      Valid Values: [use_all_dns_ips, resolve_canonical_bootstrap_servers_only]

    • groupId

      public T groupId(String value)
      Description copied from interface: ConsumerConfigFields

      group.id

      A unique string that identifies the consumer group this consumer belongs to.
      This property is required if the consumer uses either the group management functionality by using subscribe(topic) or the Kafka-based offset management strategy.

      Default: null

    • groupInstanceId

      public T groupInstanceId(String value)
      Description copied from interface: ConsumerConfigFields

      group.instance.id

      A unique identifier of the consumer instance provided by the end user.
      Only non-empty strings are permitted.
      If set, the consumer is treated as a static member, which means that only one instance with this ID is allowed in the consumer group at any time.
      This can be used in combination with a larger session timeout to avoid group rebalances caused by transient unavailability (e.g.
      process restarts).
      If not set, the consumer will join the group as a dynamic member, which is the traditional behavior.

      Default: null

      Valid Values: non-empty string

      groupInstanceId in interface ConsumerConfigFields<T extends org.swisspush.kobuka.client.base.AbstractConsumerConfigBuilder<T>>

    • sessionTimeoutMs

      public T sessionTimeoutMs(Integer value)
      Description copied from interface: ConsumerConfigFields

      session.timeout.ms

      The timeout used to detect client failures when using Kafka's group management facility.
      The client sends periodic heartbeats to indicate its liveness to the broker.
      If no heartbeats are received by the broker before the expiration of this session timeout, then the broker will remove this client from the group and initiate a rebalance.
      Note that the value must be in the allowable range as configured in the broker configuration by group.min.session.timeout.ms and group.max.session.timeout.ms.

      Default: 45000 (45 seconds)

      Valid Values:

      Importance: high

    • heartbeatIntervalMs

      public T heartbeatIntervalMs(Integer value)
      Description copied from interface: ConsumerConfigFields

      heartbeat.interval.ms

      The expected time between heartbeats to the consumer coordinator when using Kafka's group management facilities.
      Heartbeats are used to ensure that the consumer's session stays active and to facilitate rebalancing when new consumers join or leave the group.
      The value must be set lower than session.timeout.ms, but typically should be set no higher than 1/3 of that value.
      It can be adjusted even lower to control the expected time for normal rebalances.

      Default: 3000 (3 seconds)

      Valid Values:

    • partitionAssignmentStrategy

      public T partitionAssignmentStrategy(List<String> value)
      Description copied from interface: ConsumerConfigFields

      partition.assignment.strategy

      A list of class names or class types, ordered by preference, of supported partition assignment strategies that the client will use to distribute partition ownership amongst consumer instances when group management is used.
      Available options are:
      • org.apache.kafka.clients.consumer.RangeAssignor: Assigns partitions on a per-topic basis.
      • org.apache.kafka.clients.consumer.RoundRobinAssignor: Assigns partitions to consumers in a round-robin fashion.
      • org.apache.kafka.clients.consumer.StickyAssignor: Guarantees an assignment that is maximally balanced while preserving as many existing partition assignments as possible.
      • org.apache.kafka.clients.consumer.CooperativeStickyAssignor: Follows the same StickyAssignor logic, but allows for cooperative rebalancing.

      The default assignor is [RangeAssignor, CooperativeStickyAssignor], which will use the RangeAssignor by default, but allows upgrading to the CooperativeStickyAssignor with just a single rolling bounce that removes the RangeAssignor from the list.

      Implementing the org.apache.kafka.clients.consumer.ConsumerPartitionAssignor interface allows you to plug in a custom assignment strategy.

      max.partition.fetch.bytes

      The maximum amount of data per-partition the server will return.
      Records are fetched in batches by the consumer.
      If the first record batch in the first non-empty partition of the fetch is larger than this limit, the batch will still be returned to ensure that the consumer can make progress.
      The maximum record batch size accepted by the broker is defined via message.max.bytes (broker config) or max.message.bytes (topic config).
      See fetch.max.bytes for limiting the consumer request size.

      Default: 1048576 (1 mebibyte)

    • fetchMinBytes

      public T fetchMinBytes(Integer value)
      Description copied from interface: ConsumerConfigFields

      fetch.min.bytes

      The minimum amount of data the server should return for a fetch request.
      If insufficient data is available the request will wait for that much data to accumulate before answering the request.
      The default setting of 1 byte means that fetch requests are answered as soon as a single byte of data is available or the fetch request times out waiting for data to arrive.
      Setting this to something greater than 1 will cause the server to wait for larger amounts of data to accumulate which can improve server throughput a bit at the cost of some additional latency.

      Default: 1

      Valid Values: [0,...]

    • fetchMaxBytes

      public T fetchMaxBytes(Integer value)
      Description copied from interface: ConsumerConfigFields

      fetch.max.bytes

      The maximum amount of data the server should return for a fetch request.
      Records are fetched in batches by the consumer, and if the first record batch in the first non-empty partition of the fetch is larger than this value, the record batch will still be returned to ensure that the consumer can make progress.
      As such, this is not a absolute maximum.
      The maximum record batch size accepted by the broker is defined via message.max.bytes (broker config) or max.message.bytes (topic config).
      Note that the consumer performs multiple fetches in parallel.

      Default: 52428800 (50 mebibytes)

      Description copied from interface: ConsumerConfigFields

      reconnect.backoff.ms

      The base amount of time to wait before attempting to reconnect to a given host.
      This avoids repeatedly connecting to a host in a tight loop.
      This backoff applies to all connection attempts by the client to a broker.

      Description copied from interface: ConsumerConfigFields

      reconnect.backoff.max.ms

      The maximum amount of time in milliseconds to wait when reconnecting to a broker that has repeatedly failed to connect.
      If provided, the backoff per host will increase exponentially for each consecutive connection failure, up to this maximum.
      After calculating the backoff increase, 20% random jitter is added to avoid connection storms.

      Default: 1000 (1 second)

      public T autoOffsetReset(String value)
      Description copied from interface: ConsumerConfigFields

      auto.offset.reset

      What to do when there is no initial offset in Kafka or if the current offset does not exist any more on the server (e.g.
      because that data has been deleted):
      • earliest: automatically reset the offset to the earliest offset
      • latest: automatically reset the offset to the latest offset
      • none: throw exception to the consumer if no previous offset is found for the consumer's group

      check.crcs

      Automatically check the CRC32 of the records consumed.
      This ensures no on-the-wire or on-disk corruption to the messages occurred.

      max.poll.interval.ms

      The maximum delay between invocations of poll() when using consumer group management.
      This places an upper bound on the amount of time that the consumer can be idle before fetching more records.
      If poll() is not called before expiration of this timeout, then the consumer is considered failed and the group will rebalance in order to reassign the partitions to another member.
      For consumers using a non-null group.instance.id which reach this timeout, partitions will not be immediately reassigned.
      Instead, the consumer will stop sending heartbeats and partitions will be reassigned after expiration of session.timeout.ms.
      This mirrors the behavior of a static consumer which has shutdown.

    • isolationLevel

      public T isolationLevel(String value)
      Description copied from interface: ConsumerConfigFields

      isolation.level

      Controls how to read messages written transactionally.
      If set to read_committed, consumer.poll() will only return transactional messages which have been committed.
      If set to read_uncommitted (the default), consumer.poll() will return all messages, even transactional messages which have been aborted.
      Non-transactional messages will be returned unconditionally in either mode.

      Messages will always be returned in offset order.
      Hence, in read_committed mode, consumer.poll() will only return messages up to the last stable offset (LSO), which is the one less than the offset of the first open transaction.
      In particular any messages appearing after messages belonging to ongoing transactions will be withheld until the relevant transaction has been completed.
      As a result, read_committed consumers will not be able to read up to the high watermark when there are in flight transactions.

      Further, when in read_committed the seekToEnd method will return the LSO

      Default: read_uncommitted
