opensearch output

Publishes messages into an Elasticsearch index. If the index does not exist then it is created with a dynamic mapping.

# Common config fields, showing default values
output:
label: ""
opensearch:
urls: [] # No default (required)
index: "" # No default (required)
action: "" # No default (required)
id: "" # No default (required)
max_in_flight: 64
batching:
count: 0
byte_size: 0
period: ""
check: ""

Both the id and index fields can be dynamically set using function interpolations described here. When sending batched messages these interpolations are performed per message part.

Performance

This output benefits from sending multiple messages in flight in parallel for improved performance. You can tune the max number of in flight messages (or message batches) with the field max_in_flight.

This output benefits from sending messages as a batch for improved performance. Batches can be formed at both the input and output level. You can find out more in this doc.

Examples

Updating Documents

When updating documents the request body should contain a combination of a doc, upsert, and/or script fields at the top level, this should be done via mapping processors.

output:
processors:
- mapping: |
meta id = this.id
root.doc = this
opensearch:
urls: [ TODO ]
index: foo
id: ${! @id }
action: update

Fields

urls

A list of URLs to connect to. If an item of the list contains commas it will be expanded into multiple URLs.

Type: array of string

index

The index to place messages.

This field supports interpolation functions.

Type: string

action

The action to take on the document. This field must resolve to one of the following action types: index, update or delete.

This field supports interpolation functions.

Type: string

id

The ID for indexed messages. Interpolation should be used in order to create a unique ID for each message.

This field supports interpolation functions.

Type: string

pipeline

An optional pipeline id to preprocess incoming documents.

This field supports interpolation functions.

Type: string
Default: ""

routing

The routing key to use for the document.

This field supports interpolation functions.

Type: string
Default: ""

tls

Custom TLS settings can be used to override system defaults.

Type: object

tls.enabled

Whether custom TLS settings are enabled.

Type: bool
Default: false

tls.skip_cert_verify

Whether to skip server side certificate verification.

Type: bool
Default: false

tls.enable_renegotiation

Whether to allow the remote server to repeatedly request renegotiation. Enable this option if you're seeing the error message local error: tls: no renegotiation.

Type: bool
Default: false

tls.root_cas

An optional root certificate authority to use. This is a string, representing a certificate chain from the parent trusted root certificate, to possible intermediate signing certificates, to the host certificate.

Secret

This field contains sensitive information. Use a secret reference rather than a literal value.

Type: string
Default: ""

tls.root_cas_file

An optional path of a root certificate authority file to use. This is a file, often with a .pem extension, containing a certificate chain from the parent trusted root certificate, to possible intermediate signing certificates, to the host certificate.

Type: string
Default: ""

tls.client_certs

A list of client certificates to use. For each certificate either the fields cert and key, or cert_file and key_file should be specified, but not both.

Type: array of object
Default: []

tls.client_certs[].cert

A plain text certificate to use.

Type: string
Default: ""

tls.client_certs[].key

A plain text certificate key to use.

Secret

This field contains sensitive information. Use a secret reference rather than a literal value.

Type: string
Default: ""

tls.client_certs[].cert_file

The path of a certificate to use.

Type: string
Default: ""

tls.client_certs[].key_file

The path of a certificate key to use.

Type: string
Default: ""

tls.client_certs[].password

A plain text password for when the private key is password encrypted in PKCS#1 or PKCS#8 format. The obsolete pbeWithMD5AndDES-CBC algorithm is not supported for the PKCS#8 format.

Because the obsolete pbeWithMD5AndDES-CBC algorithm does not authenticate the ciphertext, it is vulnerable to padding oracle attacks that can let an attacker recover the plaintext.

Secret

This field contains sensitive information. Use a secret reference rather than a literal value.

Type: string
Default: ""

max_in_flight

The maximum number of messages to have in flight at a given time. Increase this to improve throughput.

Type: int
Default: 64

basic_auth

Allows you to specify basic authentication.

Type: object

basic_auth.enabled

Whether to use basic authentication in requests.

Type: bool
Default: false

basic_auth.username

A username to authenticate as.

Type: string
Default: ""

basic_auth.password

A password to authenticate with.

Secret

This field contains sensitive information. Use a secret reference rather than a literal value.

Type: string
Default: ""

batching

Allows you to configure a batching policy.

Type: object

batching.count

A number of messages at which the batch should be flushed. If 0 disables count based batching.

Type: int
Default: 0

batching.byte_size

An amount of bytes at which the batch should be flushed. If 0 disables size based batching.

Type: int
Default: 0

batching.period

A period in which an incomplete batch should be flushed regardless of its size.

Type: string
Default: ""

batching.check

A Bloblang query that should return a boolean value indicating whether a message should end a batch.

Type: string
Default: ""

batching.processors

A list of processors to apply to a batch as it is flushed. This allows you to aggregate and archive the batch however you see fit. Please note that all resulting messages are flushed as a single batch, therefore splitting the batch into smaller batches using these processors is a no-op.

Type: array of processor
