Properties

exitOnFailed

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

Exit if any non true return value

This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier.

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.

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.

Definitions

DockerOptions-Memory

kernelMemory

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

The maximum amount of memory the container can use.

That is, you must set the value to at least 6 megabytes.

memoryReservation

  • Type: string
  • Dynamic: ✔️
  • 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: ✔️
  • 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: ✔️
  • 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 memory.

DockerOptions

image

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

Docker image to use

Limits cpu usage.

extraHosts

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

Docker extra host to use

memory

Limits memory usage.

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
  • Dynamic: ✔️
  • Required: ❌

Docker network mode to use

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

DockerOptions-Cpu

cpus

  • Type: integer
