Warning Jobserver and all related Jobserver integrations are end of life starting October, 2024, with the exception of Public Sector customers using GovCloud or on-prem environments.
For information on the integration of S3 via Edge, go to Integrating an Amazon S3 file system via Edge.
A crawler is an automated script that ingests data from Amazon S3 to Data Catalog.
You can create, edit and delete crawlers in Collibra Data Intelligence Platform. When you synchronize Amazon S3, the crawlers are created in AWS Glue and executed. Each crawler crawls a location in Amazon S3 based on its include path. You can make an S3 bucket accessible for crawlers from the same or other AWS accounts than the account in which the S3 bucket is located. The results are stored in one AWS Glue database per domain assigned to one or more crawlers. Those databases are ingested in Data Catalog in the form of assets, attributes and relations. The databases are stored in AWS Glue until the next synchronization. At that moment, they are deleted and re-created. The crawlers in AWS Glue are deleted immediately after as the synchronization is finished.
- By default, AWS Glue allows up to 25 crawlers per account. For more information, see the AWS Glue documentation. This has consequences for Collibra:
- If you created crawlers in AWS Glue directly, Collibra can create less crawlers for synchronization.
- Because Collibra creates the crawlers in AWS Glue during synchronization, you should avoid having 25 or more crawlers in one S3 File System asset.
- You can synchronize several S3 File System assets simultaneously, but if the total number of crawlers exceeds the maximum amount in AWS Glue, synchronization will fail. Since Collibra deletes the crawlers from AWS Glue after synchronization, it is safer to synchronize each S3 File System asset at a unique time.
- Crawlers in AWS Glue can crawl multiple buckets, but in Collibra, each crawler can only crawl a single bucket.
