pluginName

  • Type: string
  • Dynamic: ❌
  • Required: ✔️
  • Default: PGOUTPUT
  • Possible Values:
    • DECODERBUFS
    • WAL2JSON
    • WAL2JSON_RDS
    • WAL2JSON_STREAMING
    • WAL2JSON_RDS_STREAMING
    • PGOUTPUT

The name of the PostgreSQL logical decoding plug-in installed on the PostgreSQL server.

If you are using a wal2json plug-in and transactions are very large, the JSON batch event that contains all transaction changes might not fit into the hard-coded memory buffer, which has a size of 1 GB. In such cases, switch to a streaming plug-in, by setting the plugin-name property to wal2json_streaming or wal2json_rds_streaming. With a streaming plug-in, PostgreSQL sends the connector a separate message for each change in a transaction.

port

  • Type: string
  • Dynamic: ✔️
  • Required: ✔️

Port of the remote server

publicationName

  • Type: string
  • Dynamic: ✔️
  • Required: ✔️
  • Default: kestra_publication

The name of the PostgreSQL publication created for streaming changes when using pgoutput.

This publication is created at start-up if it does not already exist and it includes all tables. Debezium then applies its own include/exclude list filtering, if configured, to limit the publication to change events for the specific tables of interest. The connector user must have superuser permissions to create this publication, so it is usually preferable to create the publication before starting the connector for the first time.

If the publication already exists, either for all tables or configured with a subset of tables, Debezium uses the publication as it is defined.

slotName

  • Type: string
  • Dynamic: ✔️
  • Required: ✔️
  • Default: kestra

The name of the PostgreSQL logical decoding slot that was created for streaming changes from a particular plug-in for a particular database/schema.

The server uses this slot to stream events to the Debezium connector that you are configuring. Slot names must conform to PostgreSQL replication slot naming rules, which state: "Each replication slot has a name, which can contain lower-case letters, numbers, and the underscore character."

snapshotMode

  • Type: string
  • Dynamic: ❌
  • Required: ✔️
  • Default: INITIAL
  • Possible Values:
    • INITIAL
    • ALWAYS
    • NEVER
    • INITIAL_ONLY

Specifies the criteria for running a snapshot when the connector starts.

Possible settings are:

  • INITIAL: The connector performs a snapshot only when no offsets have been recorded for the logical server name.
  • ALWAYS: The connector performs a snapshot each time the connector starts.
  • NEVER: The connector never performs snapshots. When a connector is configured this way, its behavior when it starts is as follows. If there is a previously stored LSN, the connector continues streaming changes from that position. If no LSN has been stored, the connector starts streaming changes from the point in time when the PostgreSQL logical replication slot was created on the server. The never snapshot mode is useful only when you know all data of interest is still reflected in the WAL.
  • INITIAL_ONLY: The connector performs an initial snapshot and then stops, without processing any subsequent changes.

splitTable

  • Type: string
  • Dynamic: ❌
  • Required: ✔️
  • Default: TABLE
  • Possible Values:
    • OFF
    • DATABASE
    • TABLE

Split table on separate output uris

Possible settings are:

  • TABLE: will split all rows by tables on output with name database.table
  • DATABASE: will split all rows by database on output with name database.
  • OFF: will NOT split all rows resulting a single data output.

stateName

  • Default: debezium-state

The name of Debezium state file

excludedColumns

  • Type: object
  • Dynamic: ✔️
  • Required: ❌

An optional, comma-separated list of regular expressions that match the fully-qualified names of columns to include in change event record values.

Fully-qualified names for columns are of the form databaseName.tableName.columnName.

excludedDatabases

  • Type: object
  • Dynamic: ✔️
  • Required: ❌

An optional, comma-separated list of regular expressions that match the names of databases for which you do not want to capture changes.

The connector captures changes in any database whose name is not in the excludedDatabases. Do not also set the includedDatabases connector configuration property.

excludedTables

  • Type: object
  • Dynamic: ✔️
  • Required: ❌

An optional, comma-separated list of regular expressions that match fully-qualified table identifiers for tables whose changes you do not want to capture.

The connector captures changes in any table not included in excludedTables. Each identifier is of the form databaseName.tableName. Do not also specify the includedTables connector configuration property.

includedColumns

  • Type: object
  • Dynamic: ✔️
  • Required: ❌

An optional, comma-separated list of regular expressions that match the fully-qualified names of columns to exclude from change event record values.

Fully-qualified names for columns are of the form databaseName.tableName.columnName.

includedDatabases

  • Type: object
  • Dynamic: ✔️
  • Required: ❌

An optional, comma-separated list of regular expressions that match the names of the databases for which to capture changes.

The connector does not capture changes in any database whose name is not in includedDatabases. By default, the connector captures changes in all databases. Do not also set the excludedDatabases connector configuration property.

includedTables

  • Type: object
  • Dynamic: ✔️
  • Required: ❌

An optional, comma-separated list of regular expressions that match fully-qualified table identifiers of tables whose changes you want to capture.

The connector does not capture changes in any table not included in includedTables. Each identifier is of the form databaseName.tableName. By default, the connector captures changes in every non-system table in each database whose changes are being captured. Do not also specify the excludedTables connector configuration property.
