Short answer: You can't.

It was possible in MongoDB version <= 3.6 where there was an option to bypass the validation completely using the check_keys=False option. But this option is deprecated ever since.

Although MongoDB has bypass_document_validation=True in newer versions, it won't bypass the . character for obvious reasons.

There is an open issue regarding this on JIRA (SERVER-30575) and it is still open. Also, the PyMongo specific issue related to this was raised once PYTHON-1522.

So until the SERVER-30575 issue fixed, you have no other choice.

I would suggest you rearrange your schema design to embed the key name as a value to a different key.

This may not be as generic but will push you in the right direction. Consider using the operators $mergeObjects to merge the filtered document from the priv_users array with the document in users. Filtering takes the $substr of the priv_users name field and compares it with the users name field. The resulting pipeline will be as follows

best Jdbc Item reader for large table

Asked 2021-Jun-15 at 09:05

I'm currently building an etl pipeline that pulls data from large oracle tables to mongodb, i want to know exactly what's the difference between JdbcCursor Item reader and Jdbc Paging item reader. which one of them is best suited for large tables. are they thread safe ?

...

ANSWER

Answered 2021-Jun-15 at 09:05

JdbcCursorItemReader uses a JDBC cursor (java.sql.ResultSet) to stream results from the database and is not thread-safe.

JdbcPagingItemReader reads items in pages of a configurable size and is thread-safe.

QUESTION

Is there a way to determine to which specific snapshot does an oplog slice belongs to in pbm list for mongo backups?

Asked 2021-Jun-15 at 07:35

I'm working on backup solutions for mongodb instances using percona backup manager.

When I do pbm list if the PITR option is enabled, I get the output for snapshot and oplog slice ranges.

Is there a way to determine which oplog slice range belongs to which backup from the output programmatically so that I can associate an oplog slice range to a snapshot.

...

ANSWER

Answered 2021-Jun-15 at 07:35

Slice always starts =>(greater than equal) of full snapshot time and <(less than) next full snapshot.

for example 2020-12-14T14:26:20Z [complete: 2020-12-14T14:34:39] for this backup PITR(Slice) is 2020-12-14T14:26:40 - 2020-12-16T17:27:26

if you want to restore then first restore 2020-12-14T14:26:20Z [complete: 2020-12-14T14:34:39] then apply 2020-12-14T14:26:40 - 2020-12-16T17:27:26 this slice and you'll get data till 2020-12-16T17:27:26

ANSWER

Answered 2021-Jun-14 at 18:31

The problem is MongoDB uses BSON format for storing documents. And it does not support Map objects now. There is an open issue to to add functionality close to what you're looking for. But as for now it's not implemented.

You may write your own deserializer to restore your Map object. After getting the document from the DB you'll have to transfrom certain properties into corresponding entities. Map in your case. Something like:

React App running in Heroku fails when retrieving large amounts of data

Asked 2021-Jun-14 at 18:09

I have a react application (Node back end) running on Heroku (free option) connecting to a MongoDB running on Atlas (also free option). When I connect the application from my local machine to the Atlas DB all is fine and data retrieved (all 108 K records) in about 10 seconds, smaller amounts (4-500 records) of data in much less time. The same request from the application running on Heroku to the Atlas DB fails. The application running on Heroku can retrieve a small number of records (1-10) from the same collection of (108 K records), in less than a second. As soon as I try to retrieve a couple of hundred records the system fails. Below are the logs. I included the section of the logs that show a successful retrieval of 1 record and then failing on the request for about 450 records.

I have three questions:

What is the cause of the issue?
Is there a work around in the free option of Heroku?
If there is no work around in the free option, what Heroku pay level will I need to get to and what steps will I need to take to get this working? I will probably upgrade in the future but want to prove all is working before going in that direction.

You're running out of heap memory in your node server. It might be because there's some statement that uses a lot of memory. You can try to find that or you can try to increase node memory like this.
