The first step to analyze data in real-time is to load the streaming data – often from Webhooks, in real-time to the warehouse. A common use case for a BigQuery webhook is automatically sending a notification to a service like Slack or email whenever a dataset is updated. In this article, you will learn two methods of how to load real-time streaming data from Webhook to BigQuery. Note: When architecting a Webhooks Google BigQuery integration, it’s essential to address security concerns to ensure your data remains protected. Also, when connecting BigQuery webhook, defining your webhook endpoint is essential – the address or URL that will receive the incoming data is essential.

This is the same URL from which the target application will read the data. Step 2: Preparing Data received from Webhook Webhooks post data to your specified endpoints in JSON format. It is up to you to parse the JSON objects and determine how to load them into your BigQuery data warehouse. You need to ensure the target BigQuery table is well aligned with the source data layout, specifically column sequence and data type of columns. Step 3: Loading data into Google BigQuery We can load data into BigQuery directly using API call or can create CSV file and then load into BigQuery table. Create a Python script to read data from the Webhook URL endpoint and load it into the BigQuery table. from google.cloud import bigquery import requests client = bigquery.Client() dataset_id = 'dataset_name' #replace with your dataset ID table_id = 'table_name' #replace with your table ID table_ref = client.dataset(dataset_id).table(table_id) table = client.get_table(table_ref) # API request receive data from WebHook Convert received data into rows to insert into BigQuery errors = client.insert_rows(table, rows_to_insert)# API request assert errors == [] You can store streaming data into a file by a specific interval and use the bq command-line tool to upload the files to your datasets, adding schema and data type information. In the GCP documentation of the GSUTIL tool, you can find the syntax of the bq command line. Iterate through this process as many times as it takes to load all of your tables into BigQuery. Once the data has been extracted from your application using Webhook, the next step is to upload it to the GCS. There are multiple techniques to upload data to GCS. Upload file to GCS bucket Using Gsutil: Using Gsutil utility we can upload a local file to GCS(Google Cloud Storage) bucket. gsutil cp local_folder/file_name.csv gs://gcs_bucket_name/path/to/folder/ To copy a file to GCS: Using Web console: An alternative way to upload the data from your local machine to GCS is using the web console. To use the web console option follow the below steps. Image Source First of all, you need to login to your GCP account. You must have a working Google account of GCP. In the menu option, click on storage and navigate to the browser on the left tab. If needed create a bucket to upload your data. Make sure that the name of the bucket you choose is globally unique. Click on the bucket name that you have created in step #2, this will ask you to browse the file from your local machine. Choose the file and click on the upload button. A progression bar will appear. Next, wait for the upload to complete. You can see the file is loaded in the bucket. Create Table in BigQuery Image Source Go to the BigQuery from the menu option. On G-Cloud console, click on create a dataset option. Next, provide a dataset name and location. Next, click on the name of the created dataset. On G-Cloud console, click on create table option and provide the dataset name, table name, project name, and table type. Load the data into BigQuery Table Once the table is created successfully, you will get a notification that will allow you to use the table as your new dataset. Image Source Alternatively, the same can be done using the Command Line as well. Start the command-line tool and click on the cloud shell icon shown here. The syntax of the bq command line to load the file in the BigQuery table: Note: The Autodetect flag identifies the table schema bq --location=[LOCATION] load --source_format=[FORMAT] [DATASET].[TABLE] [PATH_TO_SOURCE] [SCHEMA] [LOCATION] is an optional parameter that represents Location name like “us-east” [FORMAT] to load CSV file set it to CSV [DATASET] dataset name. [TABLE] table name to load the data. [PATH_TO_SOURCE] path to source file present on the GCS bucket. [SCHEMA] Specify the schema bq --location=US load --source_format=CSV your_dataset.your_table gs://your_bucket/your_data.csv ./your_schema.json You can specify your schema using bq command line Loading Schema Using the Web Console Image Source BigQuery will display all the distinct columns that were found under the Schema tab. Alternatively, to do the same in the command line, use the below command: bq --location=US load --source_format=CSV your_dataset.your_table gs://your_bucket/your_data.csv ./your_schema.json Your target table schema can also be autodetected: bq --location=US load --autodetect --source_format=CSV your_dataset.your_table gs://mybucket/data.csv BigQuery command-line interface allows us to 3 options to write to an existing table. The Web Console has the Query Editor which can be used for interacting with existing tables using SQL commands. Image Source Overwrite the table bq --location = US load --autodetect --replace --source_file_format = CSV your_target_dataset_name.your_target_table_name gs://source_bucket_name/path/to/file/source_file_name.csv Append data to the table bq --location = US load --autodetect --noreplace --source_file_format = CSV your_target_dataset_name.your_table_table_name gs://source_bucket_name/path/to/file/source_file_name.csv ./schema_file.json Adding new fields in the target table bq --location = US load --noreplace --schema_update_option = ALLOW_FIELD_ADDITION --source_file_format = CSV your_target_dataset.your_target_table gs://bucket_name/source_data.csv ./target_schema.json Update data into BigQuery Table The data that was matched in the above-mentioned steps not done complete data updates on the target table. The data is stored in an intermediate data table. This is because GCS is a staging area for BigQuery upload. There are two ways of updating the target table as described here. Update the rows in the target table. Next, insert new rows from the intermediate table UPDATE target_table t SET t.value = s.value FROM intermediate_table s WHERE t.id = s.id; INSERT target_table (id, value) SELECT id, value FROM intermediate_table WHERE NOT id IN (SELECT id FROM target_table); Delete all the rows from the target table which are in the intermediate table. Then, insert all the rows newly loaded in the intermediate table. Here the intermediate table will be in truncate and load mode. DELETE FROM final_table f WHERE f.id IN (SELECT id from intermediate_table); INSERT data_setname.target_table(id, value) SELECT id, value FROM data_set_name.intermediate_table; Sync your Webhook data to BigQuery Start For Free No credit card required Limitations of writing custom Scripts to stream data from Webhook to BigQuery The above code is built based on a certain defined schema from the Webhook source. There are possibilities that the scripts break if the source schema is modified. If in future you identify some data transformations need to be applied on your incoming webhook events, you would require to invest additional time and resources on it. Overload of incoming data, you might have to throttle the data moving to BQ. Given you are dealing with real-time streaming data you would need to build very strong alerts and notification systems to avoid data loss due to an anomaly at the source or destination end. Since webhooks are triggered by certain events, this data loss can be very grave for your business.
