couchbase

EXPERIMENTAL

This component is experimental and therefore subject to change or removal outside of major version releases.

Performs operations against Couchbase for each message, allowing you to store or retrieve data within message payloads.

Introduced in version 1.0.0.

# Common config fields, showing default values
label: ""
couchbase:
url: couchbase://localhost:11210 # No default (required)
username: "" # No default (optional)
password: "" # No default (optional)
bucket: "" # No default (required)
id: ${! json("id") } # No default (required)
content: "" # No default (optional)
operation: get
cas_enabled: false

When inserting, replacing or upserting documents, each must have the content property set.

Concurrent Document Mutations

To prevent read/write conflicts, Couchbase returns a Compare And Swap (CAS) value with each accessed document. Bento stores these as key/value pairs in metadata with the couchbase_cas field. Note: CAS checks are disabled by default. You can configure this by changing the value of cas_enabled: true. Future versions will see this enabled by default.

This transcoder implements behaviour matching that of gocb v1.This will apply the following behavior to the value: binary ([]byte) -> binary bytes, Binary expectedFlags. string -> string bytes, String expectedFlags. default -> JSON value, JSON expectedFlags.
rawRawBinaryTranscoder implements passthrough behavior of raw binary data. This transcoder does not apply any serialization. This will apply the following behavior to the value: binary ([]byte) -> binary bytes, binary expectedFlags. default -> error.
rawjsonRawJSONTranscoder implements passthrough behavior of JSON data. This transcoder does not apply any serialization. It will forward data across the network without incurring unnecessary parsing costs. This will apply the following behavior to the value: binary ([]byte) -> JSON bytes, JSON expectedFlags. string -> JSON bytes, JSON expectedFlags. default -> error.
