On this submit, we present you methods to configure zero-ETL integration of Amazon DocumentDB with OpenSearch Service utilizing Amazon OpenSearch Ingestion. It includes performing a full load of Amazon DocumentDB knowledge and repeatedly streaming the most recent knowledge to Amazon OpenSearch Service utilizing change streams. For different ingestion strategies, see documentation.

Answer overview

At a excessive degree, this answer includes the next steps:

  1. Allow change streams on the Amazon DocumentDB collections.
  2. Create the OpenSearch Ingestion pipeline.
  3. Load pattern knowledge on the Amazon DocumentDB cluster.
  4. Confirm the info in OpenSearch Service.

Stipulations

To implement this answer, you want the next conditions:

Zero-ETL will carry out an preliminary full load of your assortment by doing a set scan on the first occasion of your Amazon DocumentDB cluster, which can take a number of minutes to finish relying on the dimensions of the info, and it’s possible you’ll discover elevated useful resource consumption in your cluster.

Allow change streams on the Amazon DocumentDB collections

Amazon DocumentDB change stream occasions comprise a time-ordered sequence of information adjustments attributable to inserts, updates, and deletes in your knowledge. We use these change stream occasions to transmit knowledge adjustments from the Amazon DocumentDB cluster to the OpenSearch Service area.

Change streams are disabled by default; you’ll be able to allow them on the particular person assortment degree, database degree, or cluster degree. To allow change streams in your collections, full the next steps:

  4. Arrange pipeline capability for compute sources to robotically scale your pipeline based mostly on the present ingestion workload.
  5. Enter the minimal and most Ingestion OpenSearch Compute Items (OCUs). On this instance, we use the default pipeline capability settings of minimal 1 Ingestion OCU and most 4 Ingestion OCUs.

Every OCU is a mix of roughly 8 GB of reminiscence and a couple of vCPUs that may deal with an estimated 8 GiB per hour. OpenSearch Ingestion helps as much as 96 OCUs, and it robotically scales up and down based mostly in your ingest workload demand.

  1. Select the configuration blueprint and beneath Use case within the navigation pane, select ZeroETL.
  2. Choose Zero-ETL with DocumentDB to construct the pipeline configuration.

This pipeline is a mix of a supply half from the Amazon DocumentDB settings and a sink half for OpenSearch Service.

It’s essential to set a number of AWS Identification and Entry Administration (IAM) roles (sts_role_arn) with the required permissions to learn knowledge from the Amazon DocumentDB database and assortment and write to an OpenSearch Service area. This function is then assumed by OpenSearch Ingestion pipelines to ensure the fitting safety posture is all the time maintained when shifting the info from supply to vacation spot.
