Manta Flow Alation: Alation Requirements
The following are the prerequisites necessary for IBM Manta Data Lineage to connect to this third-party system, which you may choose to do at your sole discretion. Note that while these are usually sufficient to connect to this third-party system, we cannot guarantee that the connection or integration will be successful since we have no control, liability, or responsibility for third-party products or services, including for their performance.
-
Alation-Manta Data Lineage compatibility matrix:
- Alation 2020.3 (Build 5.17.0) is the lowest version of Alation supported
-
The following Alation features have to be turned on.
-
Lineage API v2 has to be enabled—the feature flag
alation.feature_flags.enable_lineage_v2
has to be set totrue
-
Virtual BI Server Sources API (GBM V2) has to be enabled—the feature flag
alation.feature_flags.enable_gbm_v2
has to be set totrue
-
It is recommended (but not necessary) to enable Swagger API documentation in case it is necessary to execute ad-hoc API queries —the feature flag
alation.feature_flags.enable_swagger
has to be set totrue
-
It should be possible to enable these features by following the instructions, but it is strongly recommended to consult Alation support before doing so:
-
Connect to the Alation server via ssh
-
Execute
sudo service alation shell
-
Execute
alation_conf alation.feature_flags.enable_lineage_v2 -s True alation.feature_flags.enable_gbm_v2 -s True alation.feature_flags.enable_swagger -s True
-
Execute
alation_action restart_alation
-
-
-
Connection parameters for Alation:
-
Alation base application URL
-
Authorization options:
-
Default mode: Use an Alation username and password to allow Manta Data Lineage to automatically create authorization tokens. After that, Manta Data Lineage will be able to automatically generate tokens whenever you need to authorize an export. Reach out to Alation support to obtain your credentials.
-
Legacy mode: Use an Alation API access token for the authorization process. You’ll need to request a new token every time you want to authorize an export, as tokens expire after 24 hours (unless longer validity is configured in Alation). Reach out to Alation support to obtain your API access token.
-
In either case, the user leveraged by Manta Data Lineage requires the
SERVER_ADMIN
role in Alation.
-
-
If HTTPs should be configured for the integration, the public certificate for the Alation application is needed
