Properties

defaultTargetSchema

  • Type: string
  • Dynamic: βœ”οΈ

  • Min length: 1

The database user

accessKeyId

  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

S3 Access Key Id. Used for S3 and Redshift copy operations.

addMetadataColumns

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

Add 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 redshift etc.) Metadata columns are creating automatically by adding extra columns to the tables with a column prefix SDC. The metadata columns are documented at here. Enabling metadata columns will flag the deleted rows by setting the _SDC_DELETED_AT metadata column. Without the addMetadataColumns option the deleted rows from singer taps will not be recongisable in Redshift.

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 Redshift.

command

  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

Override default singer command

compression

  • Type: string
  • Dynamic: ❌
  • Required: ❓
  • Default: bzip2
  • Possible Values:
    • gzip
    • bzip2

The compression method to use when writing files to S3 and running Redshift COPY.

copyOptions

  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

COPY options. Parameters to use in the COPY command when loading data to Redshift. Some basic file formatting parameters are fixed values and not recommended overriding them by custom values. They are like: CSV GZIP DELIMITER ',' REMOVEQUOTES ESCAPE.

dataFlatteningMaxLevel

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

Object type RECORD items from taps can be transformed to flattened columns by creating columns automatically. When hardDelete option is true then DELETE SQL commands will be performed in Redshift 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, hardDelete option automatically enables the addMetadataColumns option as well..

dbName

  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

The database name

defaultTargetSchemaSelectPermissions

  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

Grant USAGE privilege on newly created schemas and grant SELECT privilege on newly created tables to a specific list of users or groups. If schemaMapping is not defined then every stream sent by the tap is granted accordingly.

disableTableCache

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

Disable table cache. By default the connector caches the available table structures in Redshift at startup. In this way it doesn't need to run additional queries when ingesting data to check if altering the target tables is required. With disable_table_cache option you can turn off this caching. You will always see the most recent table structures but will cause an extra query runtime.

docker

Docker options when for the DOCKER runner

flushAllStreams

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

Flush and load every stream into Redshift 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 Redshift. When hardDelete option is true then DELETE SQL commands will be performed in Redshift 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, hardDelete option automatically enables the addMetadataColumns 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: βœ”οΈ
  • Required: ❓

The database user's password

pipPackages

  • Type: array

redshiftCopyRoleArn

  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

AWS Redshift COPY role ARN. AWS Role ARN to be used for the Redshift COPY operation. Used instead of the given AWS keys for the COPY operation if provided - the keys are still used for other S3 operations.

s3Acl

  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

AWS S3 ACL. S3 Object ACL.

s3KeyPrefix

  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

S3 Key Prefix. A static prefix before the generated S3 key names. Using prefixes you can upload files into specific directories in the S3 bucket. Default(None).

schema_mapping

  • Type: string
  • Dynamic: ❌
  • Required: ❓

Schema mapping. Useful if you want to load multiple streams from one tap to multiple Redshift schemas. If the tap sends the stream_id in <schema_name>-<table_name> format then this option overwrites the default_target_schema value. Note, that using schema_mapping you can overwrite the default_target_schema_select_permissions value to grant SELECT permissions to different groups per schemas or optionally you can create indices automatically for the replicated tables.

secretAccessKey

  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

S3 Secret Access Key. Used for S3 and Redshift copy operations.

sessionToken

  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

AWS S3 Session Token. S3 AWS STS token for temporary credentials.

skipUpdates

  • Type: boolean
  • Dynamic: ❌

slices

  • Type: integer
  • Dynamic: ❌
  • Required: ❓
  • Default: 1

number of slices to split files into prior to running COPY on Redshift. This should be set to the number of Redshift slices. The number of slices per node depends on the node size of the cluster - run SELECT COUNT(DISTINCT slice) slices FROM stv_slices to calculate this.

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 Redshift. Enabling this option will detect invalid records earlier but could cause performance degradation..

io.kestra.plugin.scripts.exec.scripts.models.DockerOptions-Memory

Properties

kernelMemory
  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

The maximum amount of kernel memory the container can use. The minimum allowed value is 4m. Because kernel memory cannot be swapped out, a container which is starved of kernel memory may block host machine resources, which can have side effects on the host machine and on other containers. See --kernel-memory details.

memory
  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

The maximum amount of memory resources the container can use. It is recommended that you set the value to at least 6 megabytes.

memoryReservation
  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

Allows you to specify a soft limit smaller than memory which is activated when Docker detects contention or low memory on the host machine. If you use memoryReservation, it must be set lower than memory for it to take precedence. Because it is a soft limit, it does not guarantee that the container doesn’t exceed the limit.

memorySwap
  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

The amount of memory this container is allowed to swap to disk. If memory and memorySwap are set to the same value, this prevents containers from using any swap. This is because memorySwap is the amount of combined memory and swap that can be used, while memory is only the amount of physical memory that can be used.

memorySwappiness
  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

The amount of memory this container is allowed to swap to disk. By default, the host kernel can swap out a percentage of anonymous pages used by a container. You can set memorySwappiness to a value between 0 and 100, to tune this percentage.

oomKillDisable
  • Type: boolean
  • Dynamic: ❌
  • Required: ❓

By default, if an out-of-memory (OOM) error occurs, the kernel kills processes in a container. To change this behavior, use the oomKillDisable option. Only disable the OOM killer on containers where you have also set the memory option. If the memory flag is not set, the host can run out of memory, and the kernel may need to kill the host system’s processes to free the memory.

  • Dynamic: βœ”οΈ
  • Required: ❓

Docker configuration file. Docker configuration file that can set access credentials to private container registries. Usually located in ~/.docker/config.json.

cpu

Limits the CPU usage to a given maximum threshold value. By default, each container’s access to the host machine’s CPU cycles is unlimited. You can set various constraints to limit a given container’s access to the host machine’s CPU cycles.

Extra hostname mappings to the container network interface configuration.

host
  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

Docker API URI.

memory

Limits memory usage to a given maximum threshold value. Docker can enforce hard memory limits, which allow the container to use no more than a given amount of user or system memory, or soft limits, which allow the container to use as much memory as it needs unless certain conditions are met, such as when the kernel detects low memory or contention on the host machine. Some of these options have different effects when used alone or when more than one option is set.

networkMode
  • Type: string

user
  • Type: string
  • Dynamic: βœ”οΈ
  • Required: ❓

User in the Docker container.

volumes
  • Type: array
  • SubType: string
  • Dynamic: βœ”οΈ
  • Required: ❓

List of volumes to mount. Must be a valid mount expression as string, example : /home/user:/app.

Volumes mount are disabled by default for security reasons; you must enable them on server configuration by setting kestra.tasks.scripts.docker.volume-enabled to true.

io.kestra.plugin.scripts.exec.scripts.models.DockerOptions-Cpu

Properties

cpus
  • Type: integer
  • Dynamic: ❌
  • Required: ❓

The maximum amount of CPU resources a container can use. For instance, if the host machine has two CPUs and you set cpus:"1.5", the container is guaranteed at most one and a half of the CPUs.
