What is Upsolver SQLake?
SQLake enables you to build reliable, maintainable, and testable processing pipelines on batch and streaming data. Define your processing pipelines using SQL in three simple steps:
- 1.Create connections to data sources and targets.
- 2.Ingest source data into a staging location in your data lake where you can inspect events, validate quality, and ensure data freshness.
- 3.Transform and refine the data using the full power of SQL Then insert, update, and delete it in your target system.
SQLake automatically manages the orchestration of tasks, scales compute resources up and down, and optimizes the output data, so you can deliver high-quality, fresh, and reliable data.
With SQLake you can:
- Lower the barrier to entry by developing pipelines and transformations using familiar SQL.
- Improve reusability and reliability by managing pipelines as code.
- Integrate pipeline development, testing, and deployment with existing CI/CD tools using a CLI.
- Eliminate complex scheduling and orchestration with always-on, automated data pipelines.
- Improve query performance with automated data lake management and optimization.
Here's an example of how to create a data pipeline in five simple steps:
1. Create an Amazon S3 connection to manage IAM credentials for jobs that
need to access data in Amazon S3
CREATE S3 CONNECTION upsolver_s3_samples
AWS_ROLE = 'arn:aws:iam::949275490180:role/upsolver_samples_role'
EXTERNAL_ID = 'SAMPLES'
READ_ONLY = TRUE;
2. Create an empty table to use as staging for the raw data.
CREATE TABLE default_glue_catalog.upsolver_samples.orders_raw_data;
3. Ingest raw data from your bucket into the staging table
CREATE JOB load_orders_raw_data_from_s3
CONTENT_TYPE = JSON
AS COPY FROM S3 upsolver_s3_samples BUCKET = 'upsolver-samples' PREFIX = 'orders/'
4. Create an output table in AWS Glue Data Catalog. The table will be accessible
in Athena once data has been added.
Note: We've defined partition_date as a partition column of type date.
This column doesn't exist in the source table and will be created in the
CREATE TABLE default_glue_catalog.upsolver_samples.orders_transformed_data(
PARTITION BY partition_date;
5. Create a job to read from the staging table, apply business logic
transformations and insert the results into the output table.
Note: It may take 3-4 minutes for the data to appear in your output table.
CREATE JOB transform_orders_and_insert_into_athena
START_FROM = BEGINNING
ADD_MISSING_COLUMNS = true
RUN_INTERVAL = 1 MINUTE
AS INSERT INTO default_glue_catalog.upsolver_samples.orders_transformed_data MAP_COLUMNS_BY_NAME
-- Use the SELECT statement to choose columns from the source and implement your business logic transformations.
orderid AS order_id, -- rename columns
MD5(customer_email) AS customer_id, -- hash or mask columns using built-in functions
customer_name, -- computed field defined later in the query
nettotal AS total,
$commit_time AS partition_date -- populate the partition column with the processing time of the event, automatically cast to DATE type
LET customer_name = customer_firstname || ' ' || customer_lastname -- create a computed column
WHERE ordertype = 'SHIPPING'
It's that simple. After the jobs are executed they run until stopped. There is no need to schedule or orchestrate them, and the compute cluster scales up and down automatically. This greatly simplifies the deployment and management of your pipelines.
