#initialize(delta: 1, initial: nil, expiry: nil, durability_level: :none, replicate_to: :none, persist_to: :none, timeout: nil, retry_strategy: nil, client_context: nil, parent_span: nil) {|self| ... } ⇒ Increment

Creates an instance of options for BinaryCollection#increment

Parameters:

  • delta (Integer) (defaults to: 1) —

    the delta for the operation

  • initial (Integer) (defaults to: nil) —

    if present, holds the initial value

  • expiry (Integer, #in_seconds, Time, nil) (defaults to: nil) —

    if set, holds the expiration for the operation

  • durability_level (Symbol) (defaults to: :none) —

    level of durability

    :none

    no enhanced durability required for the mutation

    :majority

    the mutation must be replicated to a majority of the Data Service nodes (that is, held in the memory allocated to the bucket)

    :majority_and_persist_to_active

    The mutation must be replicated to a majority of the Data Service nodes. Additionally, it must be persisted (that is, written and synchronised to disk) on the node hosting the active partition (vBucket) for the data.

    :persist_to_majority

    The mutation must be persisted to a majority of the Data Service nodes. Accordingly, it will be written to disk on those nodes.

  • replicate_to (Symbol) (defaults to: :none) —

    number of nodes to replicate

    :none

    do not apply any replication requirements.

    :one

    wait for replication to at least one node.

    :two

    wait for replication to at least two nodes.

    :three

    wait for replication to at least three nodes.

  • persist_to (Symbol) (defaults to: :none) —

    number of nodes to persist

    :none

    do not apply any persistence requirements.

    :active

    wait for persistence to active node

    :one

    wait for persistence to at least one node.

    :two

    wait for persistence to at least two nodes.

    :three

    wait for persistence to at least three nodes.

    :four

    wait for persistence to four nodes (active and replicas).

  • timeout (Integer, #in_milliseconds, nil) (defaults to: nil)
  • retry_strategy (Proc, nil) (defaults to: nil) —

    the custom retry strategy, if set

  • client_context (Hash, nil) (defaults to: nil) —

    the client context data, if set

  • parent_span (Span, nil) (defaults to: nil) —

    if set holds the parent span, that should be used for this request

Raises:

  • (ArgumentError)
