QUESTION

Accessing Aurora Postgres Materialized Views from Glue data catalog for Glue Jobs

Asked 2021-Jun-15 at 13:51

I have an Aurora Serverless instance which has data loaded across 3 tables (mixture of standard and jsonb data types). We currently use traditional views where some of the deeply nested elements are surfaced along with other columns for aggregations and such.

We have two materialized views that we'd like to send to Redshift. Both the Aurora Postgres and Redshift are in Glue Catalog and while I can see Postgres views as a selectable table, the crawler does not pick up the materialized views.

Currently exploring two options to get the data to redshift.

Output to parquet and use copy to load
Point the Materialized view to jdbc sink specifying redshift.

Wanted recommendations on what might be most efficient approach if anyone has done a similar use case.

Questions:

In option 1, would I be able to handle incremental loads?
Is bookmarking supported for JDBC (Aurora Postgres) to JDBC (Redshift) transactions even if through Glue?
Is there a better way (other than the options I am considering) to move the data from Aurora Postgres Serverless (10.14) to Redshift.

Thanks in advance for any guidance provided.

Went with option 2. The Redshift Copy/Load process writes csv with manifest to S3 in any case so duplicating that is pointless.

Regarding the Questions:

N/A
Job Bookmarking does work. There is some gotchas though - ensure Connections both to RDS and Redshift are present in Glue Pyspark job, IAM self ref rules are in place and to identify a row that is unique [I chose the primary key of underlying table as an additional column in my materialized view] to use as the bookmark.
Using the primary key of core table may buy efficiencies in pruning materialized views during maintenance cycles. Just retrieve latest bookmark from cli using aws glue get-job-bookmark --job-name yourjobname and then just that in the where clause of the mv as where id >= idinbookmark

conn = glueContext.extract_jdbc_conf("yourGlueCatalogdBConnection") connection_options_source = { "url": conn['url'] + "/yourdB", "dbtable": "table in dB", "user": conn['user'], "password": conn['password'], "jobBookmarkKeys":["unique identifier from source table"], "jobBookmarkKeysSortOrder":"asc"}

datasource0 = glueContext.create_dynamic_frame.from_options(connection_type="postgresql", connection_options=connection_options_source, transformation_ctx="datasource0")

That's all, folks

AWS Personalize: Dumping User-item interaction Dataset Created By PutEvent

Asked 2021-Jun-14 at 12:56

Following AWS Personalize documents, I successfully imported my datasets (User, Item, Interaction) from S3, created an EventTrcker, trained the model, and deployed the campaign. The solution works without any issue and I get the recommendations.

I rely on Putevent to add new user-item interaction events. I also dump those interaction events using Lambda+firehose in my s3. But I am wondering if AWS Personalize internally creates/augments the original user-item interaction dataset? How I can access and download the revised version of the dataset? I cannot see any new dataset in "Dataset groups > Datasets" rather than my original 3 datasets...

I prefer to dump it regularly from AWS Personalize to my S3 storage rather than using my own Lambda+Firehose solution.

This is the output of my Putevent call. I see 200...but not sure it works fine or not...should I see any new dataset in "Dataset groups > Datasets" created by putevents?

After thinking a little bit, I think I know what your problem is, you are using function ($keywords), but you should be using function () use ($keywords) because, in the source code, you see that it is doing $value = $callback(), but your function is awaiting $keywords, if you want to share a value, you have to use use ($keywords) again, like your second function in the where.

So, it should be:

When I combine 2 onEdit scripts, I keep getting a range error on Google sheets-Script Editor

Asked 2021-Jun-09 at 21:00

I have a shared google sheet that I use as a to-do list. I am using Script Editor. I originally had everything moving to an empty row on sheet 1. As more was added I found that the done items need to move to a second sheet. My original code moved the row from any input in column 6/F. I have tried adding a trigger to move column 7/G to sheet 2. Both codes work by themselves, but I cannot seem to combine them.

After researching this site and others, I have tried renaming onEdit, Nesting, using “my function”, recording macros. I receive the same error but the line changes depending on how I edit the code. "TypeError: Cannot read property 'range' of undefined onEdit @ Done.gs:2"

What I want to achieve,

When the task is marked complete it moves to sheet2 (Column 7/G type “yes”) When the status of a task is updated it moves it to an empty row on sheet 1 (Column 6/F words used – ongoing, pending review, later) I am also looking for a basic course to start understanding scripts and macros for google sheets. I realize that I am starting in the middle and making it harder on myself. Thank you I appreciate the feedback and recommendations!

Compare the values in two monotonic increasing vectors

I have two monotonic increasing vectors, v1 and v2 of unequal lengths. For each value in v1 (e.g., v1[1], v1[2], ...), I want to find the value in v2 that is just less than v1[i] and compute the difference.
