Steps followed to insert event data to redshift database
Have created redshift cluster with VPC. created database and schema
Created eventbridge rule with target redshift
SQL query used insert into dev.schema (a,b) VALUES (event.data.a,event.data.b)
But if the event triggers for the particular name the data is not inserted in the redshift
Is there any specific SQL query methods available to push the event data to redshift database schema

I have dozens of tables in my data source (RDS) and I am ingesting all of this data into Redshift through AWS Glue. I am currently manually creating tables in Redshift (through SQL) and then proceeding with the Crawler and AWS Glue to fill in the Redshift tables with the data flowing from RDS.
Is there a way I can create these target tables within Redshift automatically (based on the tables I have in RDS, as these will just be an exact same copy initially) and not manually create each one of them with SQL in the Redshift Query Editor section?
Thanks in advance,
I would like to copy my schema tables structure without the data from one redshift cluster to another cluster so that both clusters have the same structure.
I understand we can use UNLOAD from one Cluster to the S3 bucket and then COPY to another cluster. However, this applies to a table. Does it apply to the schema as well? I have 262 tables in my current cluster.
Would the UNLOAD and LOAD allow me to copy my schema tables to another cluster?
LOAD and UNLOAD does not define/copy a schema.
Instead, I think you could (Use Amazon Redshift as a source for AWS Schema Conversion Tool. This will 'extract' the schema for a table and give you the SQL DDL commands that can be used to create the table in another Amazon Redshift cluster.
I have a set of AWS Athena queries that I am executing manually on my S3 folder. The next step would be to get the query result and push it to a Aurora MYSQL Database. The Athena table I have created by using AWS Glue.
Please find below my queries.
Is there any AWS Service that can help in querying using the Athena Query and insert resultant rows into RDS
if yes for query 1 then, Can that service be scheduled.
Presently I have created a lambda for this operation
I am new to AWS and trying to figure out how to populate a table within an external schema, residing in Amazon Redshift. I used Amazon Glue to create a table from a .csv file that sits in a S3 bucket. I can query the newly created table via Amazon Athena.
Here is where I am stuck because my task is to take the data and populate a table living in an RedShift external schema. I tried created a Job within Glue, but had no luck.
This is where I am stuck. Am I supposed to first create an empty destination table that mirrors the table that I can query using Athena?
Thank you to anyone in advance who might be able to assist!!!
Redshift Spectrum and Athena both use the Glue data catalog for external tables. When you create a new Redshift external schema that points at your existing Glue catalog the tables it contains will immediately exist in Redshift.
-- Create the Redshift Spectrum schema
CREATE EXTERNAL SCHEMA IF NOT EXISTS my_redshift_schema
FROM DATA CATALOG DATABASE 'my_glue_database'
IAM_ROLE 'arn:aws:iam:::role/MyIAMRole'
;
-- Review the schema info
SELECT *
FROM svv_external_schemas
WHERE schemaname = 'my_redshift_schema'
;
-- Review the tables in the schema
SELECT *
FROM svv_external_tables
WHERE schemaname = 'my_redshift_schema'
;
-- Confirm that the table returns data
SELECT *
FROM my_redshift_schema.my_external_table LIMIT 10
;
Basically here I want to send a notification to AWS SNS when my target table in Redshift cluster modified (for example I load new data from S3 to this table).
But When I went through Redshift documents, the events are all at higher level(like cluster, security group), and more concern about system management, monitoring and error.
So I was wondering is there a way to use specific Redshift table as an event to trigger AWS SNS?
