Multiple instances or high concurrency settings may result a degradation of performance. System Resource Considerations: ResourceĪn instance of this component can cause high usage of this system resource. Input requirement: This component requires an incoming relationship. Restricted: This component is not restricted. State management: This component does not store state. If the Mode property is set to decompress and the file is successfully decompressed, this attribute is removed, as the MIME Type is no longer known. If the Mode property is set to compress, the appropriate MIME Type is set. If the Compression Format is set to use mime.type attribute, this attribute is used to determine the compression type. If true, will remove the filename extension when decompressing data (only if the extension indicates the appropriate compression format) and add the appropriate extension when compressing dataįlowFiles will be transferred to the success relationship after successfully being compressed or decompressedįlowFiles will be transferred to the failure relationship if they fail to compress/decompress The Property has a value of 'compress'.The Property is set to one of the following values:, ,, ,,.This Property is only considered if all of the following conditions are met: Higher levels can mean much larger memory usage such as the case with levels 7-9 for xz-lzma/2 so be careful relative to heap size. A lower value results in faster processing but less compression a value of 0 indicates no (that is, simple archiving) for gzip or minimal for xz-lzma2 compression. The compression level to use this is valid only when using gzip, deflate or xz-lzma2 compression. Valid values are: GZIP, Deflate, ZSTD, BZIP2, XZ-LZMA2, LZMA, Brotli, Snappy, Snappy Hadoop, Snappy Framed, and LZ4-Framed

Must be either 'compress' or 'decompress' Indicates whether the processor should compress content or decompress content. The table also indicates any default values. No cryptography option is set, since encryption impact on performances is out of the scope of this benchmark.

Any other properties (not in bold) are considered optional. 7-Zip 19.00 Bandizip 6.25 PeaZip 7.2.0 WinRar 5.8 WinZip 24 All applications are tested using default, out-of-the-box compression settings for the selected archive format. Compression can be much slower than gzip, and is slower than bzip2 for high levels of compression, and is most useful when a compressed file will be used many times. In the list below, the names of required properties appear in bold. Decompression speed is higher than bzip2, but lower than gzip. This processor operates in a very memory efficient way so very large objects well beyond the heap size are generally fine to process Tags:Ĭontent, compress, decompress, gzip, bzip2, lzma, xz-lzma2, snappy, snappy-hadoop, snappy framed, lz4-framed, deflate, zstd, brotli Properties: tar -cf - directory/ | (pv -s $(du -sb directory/ | awk '') -p -timer -rate -bytes > tarfile.CompressContent CompressContent Description:Ĭompresses or decompresses the contents of FlowFiles using a user-specified compression algorithm and updates the mime.type attribute as appropriate. Or if you want you can do it separately with a progress bar like this. On the newer versions of tar you can also do the following too XZ_OPT='-9e -threads=8' tar cJf directory

Let’s have a directory with a lot of files and subdirectories, to compress it all we would do tar -cf - directory/ | xz -9e -threads=8 -c - > With xz - its clear that increasing the compression level dramatically reduces its speed per megabyte, with a poor 0.276 seconds per megabyte, compared to the. This should give you a newer version of XZ that supports multi threading.

Basic info Command: install Further Information Did a small amount of research and foun. echo 'deb debian main' | sudo tee /etc/apt//packages-matoski-com.list User Story As a developer, I want migrate to using xz compression to speed up installation (decompression time) and save space on the hosting server. Since the XZ utils in Debian/Ubuntu is an old version I’ve created my own backports that I can use. And as XZ compresses single files we are gonna have to use TAR to do itĪnd since the newer version of XZ supports multi threading, we can speed up compression quite a bit I’ve needed to compress several files using XZ. zstd, appears to be the clear winner, with leading compression speed, decompression speed, and acceptable compression ratio. I’ve had an 16 GB SQL dump, and it managed to compress it down to 263 MB. A close-up inspection of the output files reveal that they are identical (130260727b) with and without -9. XZ is one of the best compression tools I’ve seen, it’s compressed files so big to a fraction of their size.
