How to send data from Lambda (Python) to Redshift through Kinesis

Asked 2019-Jul-03 at 11:32

I have a lambda function in Python that makes some stuff and returns some values that need to be inserted in Redshift. In the lambda, I push the values to Kinesis, which copy them in S3 and after that in Redshift.

The values in lambda are obtained in a string as follows:

If you wish to send streaming data to Amazon Redshift, you can use Amazon Kinesis Data Firehose. It has in-built buffering of data based on size (MB) or time (seconds) for batching writes to Amazon Redshift.

You are correct that it is not ideal to perform small INSERT operations on Redshift. It is much better to load data in bulk. So, if you need to load data on a continuous basis, Kinesis Data Firehose gives the best mix of performance.

You mention that "the kinesis stream feeds a Kinesis Firehose Stream". Feel free to write directly from the AWS Lambda function to Kinesis Data Firehose.

QUESTION

Postgres - import data with double quote

Asked 2017-Jul-14 at 15:07

I have a problem with importing tab delimited data from csv file because of double quote appearing in data e.g:

→Voice"Mail→

I am importing data using import option in pgadmin III. I specified tab as delimiter and also tried with options QUOTE and/or ESCAPE. None of this worked. I know it is issue with double quote, because I removed it from file and import succeeded. I also know this issue has already been rised (Is it possible to turn off quote processing in the Postgres COPY command with CSV format?) but I cannot use option COPY FROM because I am importing data to remote DB and relative path to file on my PC is not accepted. I want to avoid modifying input file because it might be of huge size.

If you want to preserve the double quotes, set the QUOTE to something else (i would use a character that does not exist in your data file).

QUESTION

Django bulk_create raises "Database is in recovery mode"

Asked 2017-Jun-27 at 03:00

Requirements:

Upload ~15MB csv file and then bulk_create
One round it task id to 100k records.
Next round it will remove existing records and INSERT INTO again.

My guess:
I am suspecting that sequence_id overflow is the root cause of my problem
Because it used to be able to uploaded before this time, but broken just for now and could not be able to upload it again

Here is my postgres log:

Well, the error log clearly says it's not your fault.

2017-06-23 04:55:21.100 UTC [19656] DETAIL: The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory.
2017-06-23 04:55:21.100 UTC [19656] HINT: In a moment you should be able to reconnect to the database and repeat your command.

Emphasis mine. But you are still doing this the wrong way! The right way to load large amounts of data into postgresql is using COPY

COPY moves data between PostgreSQL tables and standard file-system files. COPY TO copies the contents of a table to a file, while COPY FROM copies data from a file to a table (appending the data to whatever is in the table already). COPY TO can also copy the results of a SELECT query.
