The AWS Glue Schema Registry Serializer/Deserializer enables Java developers to easily integrate their Apache Kafka and AWS Kinesis applications with AWS Glue Schema Registry. Use ROW FORMAT SERDE to explicitly specify the type of SerDe that Athena should use when it reads and writes data to the table. Learn more Amazon Redshift Spectrum uses external tables to query data stored in S3. Anyways I used AWS Glue to create the schema on demand using the opencsv SerDe to do the job. For example I told my SerDe what the escape characters are/etc. To Use a SerDe in Queries. As of version 2.0, Glue supports Python 3, which you should use in your development. Use explain to understand the query you are writing 5. use explain to minimize raws (small table X small table = maybe equals big table) 6. copy small tables to all data nodes (redshift/hive) 7. use hints if possible. When creating a table, you can pass an empty list of columns . The catalog database in which to create the new table. Architecture Design (image-1) Extract. GSR doesn't require any urls to be passed as it's centrally hosted by AWS. You can allocate from 2 to 100 DPUs; the default is 10. max_capacity is a mutually exclusive option with number_of_workers and worker_type. Athena does not support custom SerDes. I have encountered an issue with spectrum failing to scan invalid JSON data even though SerDe parameter ignore.malformed.json = true for an AWS Glue table.
