Properties

from

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

The raw data from a tap.

host

  • Type: string
  • Dynamic: ✔️
  • Required: ✔️
  • Min length: 1

The database hostname.

port

  • Type: integer
  • Dynamic: ❌
  • Required: ✔️

The database port.

stateName

  • Type: string
  • Dynamic: ✔️
  • Required: ✔️
  • Default: singer-state

The name of Singer state file stored in KV Store.

username

  • Type: string
  • Dynamic: ✔️
  • Required: ✔️
  • Min length: 1

The database user.

addMetadataColumns

  • Type: boolean
  • Dynamic: ❌
  • Required: ❌
  • Default: false

Add singer Metadata columns.

Metadata columns add extra row level information about data ingestions, (i.e. when was the row read in source, when was inserted or deleted in postgres etc.) Metadata columns are creating automatically by adding extra columns to the tables with a column prefix SDC. The column names are following the stitch naming conventions. Enabling metadata columns will flag the deleted rows by setting the _SDC_DELETED_AT metadata column. Without the add_metadata_columns option the deleted rows from singer taps will not be recognisable in Postgres.

batchSizeRows

  • Type: integer
  • Dynamic: ❌
  • Required: ❌
  • Default: 100000

Maximum number of rows in each batch.

At the end of each batch, the rows in the batch are loaded into Postgres.

command

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

Override default singer command.

containerImage

  • Type: string
  • Dynamic: ✔️
  • Required: ❌
  • Default: python:3.10.12

The task runner container image, only used if the task runner is container-based.

dataFlatteningMaxLevel

  • Type: integer
  • Dynamic: ❌
  • Required: ❌
  • Default: 0

Object type RECORD items from taps can be transformed to flattened columns by creating columns automatically.

When value is 0 (default) then flattening functionality is turned off.

dbName

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

The database name.

defaultTargetSchema

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

Name of the schema where the tables will be created.

If schemaMapping is not defined then every stream sent by the tap is loaded into this schema.

defaultTargetSchemaSelectPermission

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

Grant USAGE privilege on newly created schemas and grant SELECT privilege on newly created.

docker

Deprecated, use 'taskRunner' instead

flushAllStreams

  • Type: boolean
  • Dynamic: ❌
  • Required: ❌
  • Default: false

Flush and load every stream into Postgres when one batch is full.

Warning: This may trigger the COPY command to use files with low number of records..

hardDelete

  • Type: boolean
  • Dynamic: ❌
  • Required: ❌
  • Default: false

Delete rows on Postgres.

When hard_delete option is true then DELETE SQL commands will be performed in Postgres to delete rows in tables. It's achieved by continuously checking the _SDC_DELETED_AT metadata column sent by the singer tap. Due to deleting rows requires metadata columns, hard_delete option automatically enables the add_metadata_columns option as well.

maxParallelism

  • Type: integer
  • Dynamic: ❌
  • Required: ❌
  • Default: 16

Max number of parallel threads to use when flushing tables.

parallelism

  • Type: integer
  • Dynamic: ❌
  • Required: ❌
  • Default: 0

The number of threads used to flush tables.

0 will create a thread for each stream, up to parallelism_max. -1 will create a thread for each CPU core. Any other positive number will create that number of threads, up to parallelism_max.

password

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

The database user's password.

pipPackages

  • Type: array
  • SubType: string
  • Dynamic: ✔️
  • Required: ❌

Override default pip packages to use a specific version.

primaryKeyRequired

  • Type: boolean
  • Dynamic: ❌
  • Required: ❌
  • Default: true

Log based and Incremental replications on tables with no Primary Key cause duplicates when merging UPDATE events.

When set to true, stop loading data if no Primary Key is defined.

taskRunner

  • Type: TaskRunner
  • Dynamic: ❌
  • Required: ❌
  • Default: { "type": "io.kestra.plugin.scripts.runner.docker.Docker" }

The task runner to use.

Task runners are provided by plugins, each have their own properties.

validateRecords

  • Type: boolean
  • Dynamic: ❌
  • Required: ❌
  • Default: false

Validate every single record message to the corresponding JSON schema.

This option is disabled by default and invalid RECORD messages will fail only at load time by Postgres. Enabling this option will detect invalid records earlier but could cause performance degradation..
