QUESTION
We have a few tables in BigQuery that are being updated nightly, and then we have a deduplication process doing garbage collection slowly.
To ensure that our UI is always showing the latest, we have a view setup for each table that simply does a SELECT WHERE on the newest timestamp record_id combination
We're about to setup partitioning and clustering to optimize query scope/speed and I couldn't find a clear answer in Google documentation on whether the view of that table will still have partitioned queries or it will end up querying all data.
Alternatively when we create the view, can we include the partition and cluster on in the query that builds the view?
...ANSWER
Answered 2021-May-10 at 18:57If you're talking about a logical view, then yes if the base table it references is clustered/partitioned it will use those features if they're referenced from the WHERE clause. The logical view doesn't have its own managed storage, it's just effectively a SQL subquery that gets run whenever the view is referenced.
If you're talking about a materialized view, then partitioning/clustering from the base table isn't inherited, but can be defined on the materialized view. See the DDL syntax for more details: https://cloud.google.com/bigquery/docs/reference/standard-sql/data-definition-language#create_materialized_view_statement

My question is similar to this one: MySQL concatenate values from one table into a record of another
But it's not the same, I think because I'm trying to make use of multiple concatenated columns from several other tables.
Here are my tables:
...ANSWER
Answered 2021-May-02 at 18:53So you have a Cartesian product between Collaborators and Images. Thus both are multiplied by the number of results in the other.
You could run multiple queries and then write application code to append the results into your greater JSON document.
Or you could use correlated subqueries:

Regarding this method of preventing the insertion of duplicates:
...ANSWER
Answered 2021-Apr-26 at 00:08You are correct on the "snapshot" point: any insertions into table1 in this query will not affect the LEFT JOIN table1.
But you would still need a DISTINCT to guarantee uniqueness from the queried data.
QUESTION
I was trying to clean up duplicates in an excel file using dedupe. The code worked fine at first and the code itself is simple. But whenever I run the code I get the below error. The code works fine if I delete all the temp files, restart pycharm or restart my computer and it won't run for the second time.
The data file is a csv file with a list of random similar name in column A with header as 'Name'. Please help tp resolve. Thank you. Code
...ANSWER
Answered 2021-Mar-14 at 17:23The answer is in the error:
You need to either turn off multiprocessing or protect the calls to the Dedupe methods with a

QUESTION
Using ElasticSearch in Amazon as search engine. Lately discussed with one of developers tactics for Upsert.
In my view (i am not an well experienced ES Developer) it's ok to have a complex key as _id, e.g. Result-1, Data-2, etc. It will help on Upsert and data deduplication. But concern was raised about key datatype. Long key, such as string, Sha1-digest, hex, etc — could affect search performance, and better to have some short keys or pass it to ES without predefined _id and deduplicate with document body or some specific properties.
I haven't read anything about ID performance — from Official docs to medium/blogs.
Is the concern right and I should follow it?
Thank you!
...ANSWER
Answered 2021-Mar-10 at 14:32The concern about using custom ID fields is on the indexing phase because with the auto generated ones Elasticsearch can safely index the document without querying for uniqueness. If you are OK with your indexing rate then you should be fine.
If you look in the docs on the Tune for Search speed , there is no advice about using auto generated ids.
Relevant reads.

After starting the verification system on the site, I got an error in the database
MySQL Query Error:
...ANSWER
Answered 2021-Feb-05 at 12:00If your db is hosted on a Unix-based system, or if lower_case_table_names is set to 0, MariaDB has case sensitive table names, so you need to use b_forum and b_file, not B_FORUM and B_FILE. See the manual. Your CREATE TABLE statement works fine in this demo if you match the case of the other table declarations.
QUESTION
I am facing a strange issue in SQS. Let me simplify my use-case, I have 7 messages in the FIFO queue and my standalone app should keep-on polling the messages in the same sequence for my business case infinitely. For instance, my app read message1 and after some business processing, the app will delete it and repost the same message into the same queue(tail of the queue), and these steps will be continued for the next set of messages endlessly. Here, my expectation is my app will be polling the message continuously and doing the operations based on the messages in the queue in the same sequence, but that's where the problem arises. When the message is read from the queue for the very first time, delete it, and repost the same message into the same queue, even after the successful sendMessageResult, the reposted message is not present in the queue.
I have included the below code to simulate the issue, briefly, Test_Queue.fifo queue with Test_Queue_DLQ.fifo configured as reDrivePolicy is created. At the very first time after creating the queue, the message is posted -> "Test_Message" into Test_Queue.fifo queue(Getting the MessageId in response ) and long-polling the queue to read the message, and after iterating the ReceiveMessageResult#getMessages, deleting the message(Getting MessageId in response). Again, after the successful deletion of the message, the same message is reposted into the tail of the same queue(Getting the MessageId in response). But, the reposted message is not present in the queue. When, I checked the AWS admin console the message count is 0 in the Messages available and Messages in flight sections and the reposted message is not even present in Test_Queue_DLQ.fifo queue. As per the SQS docs, if we delete the message, even if it is present in flight mode should be removed, so reposting the same message should not be an issue. I suspect on SQS side, where they are performing some equals comparison and skipping the same message during in visibleTimeOut interval to avoid deduplication of the same message in the distributed environment, but couldn't get any clear picture.
Code snippet to simulate the above issue
...ANSWER
Answered 2021-Jan-22 at 11:51From Using the Amazon SQS message deduplication ID:
The message deduplication ID is the token used for deduplication of sent messages. If a message with a particular message deduplication ID is sent successfully, any messages sent with the same message deduplication ID are accepted successfully but aren't delivered during the 5-minute deduplication interval.
Therefore, you should supply a different Deduplication ID each time the message is placed back onto the queue.

Install deduplication
You can use deduplication like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
