            Replicating data from MySQL to BigQuery using GCP Data Fusion - Getting issue with 'Date' datatype
            Asked 2021-Jun-06 at 03:38

            I wanted to replicate Mysql tables held in GCP Compute Engine to the GC BigQuery. I referred this document : https://cloud.google.com/data-fusion/docs/tutorials/replicating-data/mysql-to-bigquery. so I Decided to use GCP Data Fusion for the Job.

            Everything works fine and the Data is replicated in Bigquery. So I was testing different datatype support for this Replication.

            Where I come up with issue in this Replication Pipeline, So whenever I try to put the 'DATE' datatype Column for the Data fusion replication, the whole table (Which contain 'DATE' Column) doesn't show up in BigQuery

            It Creates the table with schema same as source and 'Date' datatype also present in Bigquery, and I have use the same Date format as supported by BigQuery.

            I also gone through Data fusion logs, It shows pipeline is Loading the data perfectly fine into BigQuery, Also catches the new rows added into Mysql Table from source Mysql DB with inserts and updates as well. But somehow rows are not getting into Bigquery.

            Did anyone used Data fusion Replication with 'Date' column Datatype ? Is this issue with BigQuery or Data Fusion ? Do I need to provide any manual setting in the BigQuery ? Can anyone please provide inputs on this ?

            Assuming you are using Cloud Data Fusion to just get data from CloudSQL MySQL to GCP

            There are a few existing questions/docs that have been discussed in the past

            If you are indeed trying to use Cloud Data Fusion's Replication feature to replicate your db tables then connecting to a private CloudSQL MySQL instance is not supported yet.

            How to make GCP Data Fusion MySQL Replication work well with DateTime columns
            Asked 2021-Apr-16 at 03:00

            I managed to have MySQL tables replicated into BigQuery fairly easily by following this article on Cloud Data Fusion Replication. However, there's an issue with the DateTime columns. All the DateTime columns have been replicated into BigQuery using a 1970's date. Does anyone know how to fix this?

            Here is the original MySQL data:
            And here's the replicated data in BigQuery

            ANSWER

            Answered 2021-Apr-16 at 03:00

            I figured another way. You can simulate MySQL replication into BigQuery by making your own batch pipeline, then schedule that pipeline to run at the frequency you want. The MySQL setup is easy to do. Just follow the instructions to install the MySQL driver here. Then you setup your MySQL data source and your BigQuery Sink. The DateTime columns in MySQL should be marked as TimeStamps and their corresponding columns in BigQuery must be of type DateTime.

            MySQL Data Source Configs

            BigQuery Sink Configs

            Finally, you can make a BigQuery Execution Action before the MySQL Source to fetch the id or time of the latest record you have replicated.

            GCP Data Fusion HTTP post-run plugin errors
            Asked 2020-Jul-16 at 09:15

            from CDAP documentation exists an HTTPS post-run plugin to trigger pipeline start based on the successful execution of another pipeline (Scheduling). I'm trying to use this functionality in GCP Data Fusion but the plugin even if installed (because I can see it from Control Center) seems to be not available.

            I also tried to install manually the plugin HTTP Plugin v2.2.0 as stated in the documentation but has only sink and source action. Also if I try to use the plugin an error is displayed

            HTTP Properties 1.2.0 (No widgets JSON found for the plugin. Please check the documentation on how to add.)

            this error seems related to the fact that Data Fusion is trying to use version 1.2.0 (the one already installed) with properties of version 2.2.0.

            Any suggestions on how to solve this issue?

            Update

            I can see the two vesions http-plugin from Control Center

            but I cannot set the version

            Problem about http plugin hasn't been solved but I found the existence of pipeline trigger to execute pipeline based on status of another pipeline, this feateure is only available with Enterprise edition.

            Depending on the version of the you Data Fusion instance, it may still be defaulting to the old version of the plugin. To select the new version of the plugin you should:

            1. Navigate to the Studio
            2. Hover your mouse over the HTTP plugin in the sidebar
            3. After a second or so, a box will appear with the plugin details. You will see the current version of the plugin and a button beside it that says "Change", click on this button. If you don't see this button that means you only have one version of the plugin in your instance.
            4. You will see a list of all the versions of the plugin in this instance, select the one you want. The version you select will be the new default version.

            You should now be able to use v2.2.0 of the plugin.

            The specific quota related to DISKS_TOTAL_GB is the Persistent disk standard (GB) as you can see in the Disk quotas documentation.

            You can edit this quota by region in the Cloud Console of your project by going to the IAM & admin page => Quotas and select only the metric Persistent Disk Standard (GB).

            The service account is created in the tenant project associated to your Data Fusion instance (that's why the email suffix should be a random identifier + '-tp'). Therefore, you can't see it in your project but you can add the desired permissions in the IAM tab.
