Introduced in version 4.32.2. [tabs] ====== Common:: + -- ```yml # Common config fields, showing default values input: label: "" schema_registry: url: "" # No default (required) auto_replay_nacks: true ``` -- Advanced:: + -- ```yml # All config fields, showing default values input: label: "" schema_registry: url: "" # No default (required) include_deleted: false subject_filter: "" fetch_in_order: true tls: enabled: false skip_cert_verify: false enable_renegotiation: false root_cas: "" root_cas_file: "" client_certs: [] auto_replay_nacks: true oauth: enabled: false consumer_key: "" consumer_secret: "" access_token: "" access_token_secret: "" basic_auth: enabled: false username: "" password: "" jwt: enabled: false private_key_file: "" signing_method: "" claims: {} headers: {} ``` -- ====== == Metadata This input adds the following metadata fields to each message: ```text - schema_registry_subject - schema_registry_version ``` You can access these metadata fields using xref:configuration:interpolation.adoc#bloblang-queries[function interpolation]. == Examples [tabs] ====== Read schemas:: + -- Read all schemas (including deleted) from a Schema Registry instance which are associated with subjects matching the `^foo.*` filter. ```yaml input: schema_registry: url: http://localhost:8081 include_deleted: true subject_filter: ^foo.* ``` -- ====== == Fields === `url` The base URL of the schema registry service. *Type*: `string` === `include_deleted` Include deleted entities. *Type*: `bool` *Default*: `false` === `subject_filter` Include only subjects which match the regular expression filter. All subjects are selected when not set. *Type*: `string` *Default*: `""` === `fetch_in_order` Fetch all schemas on connect and sort them by ID. Should be set to `true` when schema references are used. *Type*: `bool` *Default*: `true` Requires version 4.37.0 or newer === `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` Requires version 3.45.0 or newer === `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. [CAUTION] ==== This field contains sensitive information that usually shouldn't be added to a config directly, read our xref:configuration:secrets.adoc[secrets page for more info]. ==== *Type*: `string` *Default*: `""` ```yml # Examples root_cas: |- -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- ``` === `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*: `""` ```yml # Examples root_cas_file: ./root_cas.pem ``` === `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` *Default*: `[]` ```yml # Examples client_certs: - cert: foo key: bar client_certs: - cert_file: ./example.pem key_file: ./example.key ``` === `tls.client_certs[].cert` A plain text certificate to use. *Type*: `string` *Default*: `""` === `tls.client_certs[].key` A plain text certificate key to use. [CAUTION] ==== This field contains sensitive information that usually shouldn't be added to a config directly, read our xref:configuration:secrets.adoc[secrets page for more info]. ==== *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. [CAUTION] ==== This field contains sensitive information that usually shouldn't be added to a config directly, read our xref:configuration:secrets.adoc[secrets page for more info]. ==== *Type*: `string` *Default*: `""` ```yml # Examples password: foo password: ${KEY_PASSWORD} ``` === `auto_replay_nacks` Whether messages that are rejected (nacked) at the output level should be automatically replayed indefinitely, eventually resulting in back pressure if the cause of the rejections is persistent. If set to `false` these messages will instead be deleted. Disabling auto replays can greatly improve memory efficiency of high throughput streams as the original shape of the data can be discarded immediately upon consumption and mutation. *Type*: `bool` *Default*: `true` === `oauth` Allows you to specify open authentication via OAuth version 1. *Type*: `object` === `oauth.enabled` Whether to use OAuth version 1 in requests. *Type*: `bool` *Default*: `false` === `oauth.consumer_key` A value used to identify the client to the service provider. *Type*: `string` *Default*: `""` === `oauth.consumer_secret` A secret used to establish ownership of the consumer key. [CAUTION] ==== This field contains sensitive information that usually shouldn't be added to a config directly, read our xref:configuration:secrets.adoc[secrets page for more info]. ==== *Type*: `string` *Default*: `""` === `oauth.access_token` A value used to gain access to the protected resources on behalf of the user. *Type*: `string` *Default*: `""` === `oauth.access_token_secret` A secret provided in order to establish ownership of a given access token. [CAUTION] ==== This field contains sensitive information that usually shouldn't be added to a config directly, read our xref:configuration:secrets.adoc[secrets page for more info]. ==== *Type*: `string` *Default*: `""` === `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. [CAUTION] ==== This field contains sensitive information that usually shouldn't be added to a config directly, read our xref:configuration:secrets.adoc[secrets page for more info]. ==== *Type*: `string` *Default*: `""` === `jwt` BETA: Allows you to specify JWT authentication. *Type*: `object` === `jwt.enabled` Whether to use JWT authentication in requests. *Type*: `bool` *Default*: `false` === `jwt.private_key_file` A file with the PEM encoded via PKCS1 or PKCS8 as private key. *Type*: `string` *Default*: `""` === `jwt.signing_method` A method used to sign the token such as RS256, RS384, RS512 or EdDSA. *Type*: `string` *Default*: `""` === `jwt.claims` A value used to identify the claims that issued the JWT. *Type*: `object` *Default*: `{}` === `jwt.headers` Add optional key/value headers to the JWT. *Type*: `object` *Default*: `{}`
