The temporary files aren't deleted as far as I see; consider using the tempfile module to allocate and delete temporary files automatically. Also, while the string to bytes conversion works as is, it's also brittle when used with large files, e. I'd suggest passing in gz. Unless I'm mistaken that should keep the bytes in order; if not you could still pass in a function that converts only the downloaded chunk to bytes and calls gz. Sign up to join this community.

If you were to extract something a single file from the zip file, then yes, gzipping that will of course be okay.

Make sure that the gzipped files are how you expect them i. Probably not what you want. As argued above that's probably not advisable unless you know that the data fits into memory. If it does, sure, why not. Some more remarks: The zipfile import is unused, as mentioned above. Prefer os. Sign up or log in Sign up using Google. Sign up using Facebook.

I have compressed log files I'm trying to store in S3 using django-storages s3 backend, but when I inspect the files I discover that S3 stored them in their uncompressed form. I have done some digging and discovered that django-storages is properly identifying my files as gzipped, but setting that as a ContentEncoding argument so that S3 interprets the data as gzip for HTTP transfer encoding and uncompresses it at the HTTP layer at put time.

This feels undesirable with MB compressed log files. I can create a pull request, that would fix this for my use case, but I would like to understand what is expected and what option is least likely to break other people's use cases. Options for fixing this:. If you have any thoughts on what kind of approach you would like to see taken I can take them and get a pull request submitted for review.

This appears to be related to as opened by ldng. Perhaps understanding the use case that was supported by that change could help me know how to handle this for my use case.

Hi skruger sorry can we discuss here before adding a setting in ? I think the proper fix is that we shouldn't override any setting given by the user. So you could add to your file field or your storage something like:. We can certainly discuss this. I added the configuration option in to allow someone to configure the broken behavior if they were dependent on it.

There appears to be some confusion about what the Content-Encoding header means which is why the current behavior that was introduced after the 1. If needed I could work on a change that actually solves the problem of how to serve gzip encoded assets. I found a post that talks about how to serve gzip encoded assets using Content-Encoding in the object's metadata in S3.

The correct behavior for serving static assets is setting Content-Encoding in the object's metadata, storing a compressed asset, and providing the Content-Encoding: gzip when a user downloads the asset. Instead the library is sending the header on upload to S3 requests so the asset is decompressed for storage. Anyone who was trying to compress their assets probably missed that it wasn't really working because when they referenced their assets they came down uncompressed with no content encoding instead of compressed with content-encoding: gzip.In the decade since it was first released, S3 storage has become essential to thousands of companies for file storage.

While using S3 in simple ways is easy, at larger scale it involves a lot of subtleties and potentially costly mistakes, especially when your data or team are scaling up.

Without further ado, here are the ten things about S3 that will help you avoid costly mistakes. Machine data holds hidden secrets that deliver true insights about the operational health of your AWS infrastructure. Learn more about operational visibility from AWS today! Getting data into and out of S3 takes time.

Cutting down time you spend uploading and downloading files can be remarkably valuable in indirect ways — for example, if your team saves 10 minutes every time you deploy a staging build, you are improving engineering productivity significantly. S3 is highly scalable, so in principle, with a big enough pipe or enough instances, you can get arbitrarily high throughput. A good example is S3DistCp, which uses many workers and instances. The first takeaway from this is that regions and connectivity matter.

More surprisingly, even when moving data within the same region, Oregon a newer region comes in faster than Virginia on some benchmarks. If your servers are in a major data center but not in EC2, you might consider using DirectConnect ports to get significantly higher bandwidth you pay per port.

You have to pay for that too, the equivalent of months of storage cost for the transfer in either direction. Secondly, instance types matter.

Thirdly, and critically if you are dealing with lots of items, concurrency matters. Each S3 operation is an API request with significant latency — tens to hundreds of milliseconds, which adds up to pretty much forever if you have millions of objects and try to work with them one at a time.

So what determines your overall throughput in moving many objects is the concurrency level of the transfer: How many worker threads connections on one instance and how many instances are used.

Many common S3 libraries including the widely used s3cmd do not by default make many connections at once to transfer data. Another approach is with EMR, using Hadoop to parallelize the problem.

For multipart uploads on a higher-bandwidth network, a reasonable part size is 25—50MB. Finally, if you really have a ton of data to move in batches, just ship it. Okay, we might have gotten ahead of ourselves. Before you put something in S3 in the first place, there are several things to think about.

One of the most important is a simple question:. Remember, large data will probably expire — that is, the cost of paying Amazon to store it in its current form will become higher than the expected value it offers your business.If you've got a moment, please tell us what we did right so we can do more of it.

You can unload the result of an Amazon Redshift query to your Amazon S3 data lake in Apache Parquet, an efficient open columnar storage format for analytics. Parquet format is up to 2x faster to unload and consumes up to 6x less storage in Amazon S3, compared with text formats.

This enables you to save data transformation and enrichment you have done in Amazon S3 into your Amazon S3 data lake in an open format. The results of the query are unloaded. This approach saves the time required to sort the data when it is reloaded. If your query contains quotation marks for example to enclose literal valuesput the literal between two sets of single quotation marks—you must also enclose the query between single quotation marks:.

The object names are prefixed with name-prefix. The COPY command automatically reads server-side encrypted files during the load operation.

If a field contains delimiters, double quotation marks, newline characters, or carriage returns, then the field in the unloaded file is enclosed in double quotation marks. A double quotation mark within a data field is escaped by an additional double quotation mark. For more information about Apache Parquet format, see Parquet. Specifies the partition keys for the unload operation. UNLOAD automatically partitions output files into partition folders based on the partition key values, following the Apache Hive convention.

The row count unloaded to each file. The total file size of all files unloaded and the total row count unloaded to all files. Adds a header line containing column names at the top of each output file. The default delimiter for text files is a pipe character. The default delimiter for CSV files is a comma character. The AS keyword is optional. Alternatively, specify a delimiter that isn't contained in the data. Unloads the data to a file where each column width is a fixed length, rather than separated by a delimiter.

Specifies that the output files on Amazon S3 are encrypted using Amazon S3 server-side encryption or client-side encryption. For more information, see Unloading Encrypted Data Files.

If you unload data using a master symmetric key, you must supply the same key when you COPY the encrypted data. Specifies the master symmetric key to be used to encrypt data files on Amazon S3. Unloads data to one or more bzip2-compressed files per slice.

Each resulting file is appended with a. Unloads data to one or more gzip-compressed files per slice. Unloads data to one or more Zstandard-compressed files per slice. Places quotation marks around each unloaded data field, so that Amazon Redshift can unload data values that contain the delimiter itself.

For example, if the delimiter is a comma, you could unload and reload the following data successfully:.If you've got a moment, please tell us what we did right so we can do more of it.

When uploading data from a file, you must provide the object's key name. If you don't, the API uses the file name for the key name. When uploading data from a stream, you must provide the object's key name.

To set advanced upload options—such as the part size, the number of threads when uploading the parts concurrently, metadata, the storage class, or ACL—use the TransferUtilityUploadRequest class. The following C example uploads a file to an Amazon S3 bucket in multiple parts.

It shows how to use various TransferUtility. Upload overloads to upload a file. Each successive call to upload replaces the previous upload. NET Code Examples.

Using the AWS.Browsers will honor the content-encoding header and decompress the content automatically. In practice, all real browsers accept it.

Most programming language HTTP libraries also handle it transparently but not boto3, as demonstrated above. It is worth noting that curl does not detect compression unless you have specifically asked it to. I strongly recommend adding --compressed to your.
