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.

addUpsertIndexes

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

Whether the Target should create column indexes on the important columns used during data loading.

These indexes will make data loading slightly slower but the deduplication phase much faster. Defaults to on for better baseline performance.

batchDetectionThreshold

  • Type: integer
  • Dynamic:
  • Required:

How often, in rows received, to count the buffered rows and bytes to check if a flush is necessary.

There's a slight performance penalty to checking the buffered records count or bytesize, so this controls how often this is polled in order to mitigate the penalty. This value is usually not necessary to set as the default is dynamically adjusted to check reasonably often.

Default is 5000, or 1/40th maxBatchRows

beforeRunSql

  • Type: string
  • Dynamic:
  • Required:

Raw SQL statement(s) to execute as soon as the connection to Postgres is opened by the target.

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

cpu

Limits cpu usage.

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.

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.

  • Type: string
  • Dynamic: ✔️
  • Required:

Docker network mode to use

cpus

  • Type: integer
  • Dynamic:
  • Required:
