Is it possible to enable GRPC message compression in server? (Python)

由 [亡魂溺海] 提交于 2020-01-06 06:57:48
问题 I have a gRPC client (in Java) sending requests to a server (written in Python). I need to enable both request compression and response compression. There is good documentation on how to enable compression on the client side. I have managed to compress the request like so: response = blockingStub.withCompression("gzip").method(request) However, I cannot find any documentation on how to compress the server response (also). It seems that there is almost no documentation (or examples) on how to

问题 How can I use all cpu cores in my server(has 4 cores) linux Debian over OpenVZ to gzipping faster one big file ? I am trying to use these commands but I can not put the pieces together get number of cores CORES=$(grep -c '^processor' /proc/cpuinfo) this for split big file in more split -b100 file.big this for use gzip command with multiple core find /source -type f -print0 | xargs -0 -n 1 -P $CORES gzip --best I don't know if this is the best way for optimize gzip process of big files.. 回答1:

How to make a compressed file directly usable as a regular file?

由 我的梦境 提交于 2020-01-05 06:44:29
问题 We have a custom compressor for genomic data called CRAM, and althogugh it provides superior compression people are afraid to use it, because it is not-so-easy to handle with bioinformatic tools as "regular" files. We would like to allow compressed file to be used for example as parameters to scripts, be opened in GUIs, etc. just like classic files. Like a named pipe or block device file that automatically executes the unzip command whenever it is read from. If it is easy to copy from system

Library to compress text data and store it as text

由 ￣綄美尐妖づ 提交于 2020-01-05 04:31:08
问题 I want to store web pages in compressed text files (CSV). To achieve the optimal compression, I would like to provide a set of 1000 web pages. The library should then spend some time creating the optimal "dictionary" for this content. One obvious "dictionary" entry could be <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> , which could get stored as %1 or something like that because it is present on almost all web pages. By creating a customized

Using Wcf with gzip compression

由 不羁岁月 提交于 2020-01-04 05:15:08
问题 We have a wcf service that takes large amount of data. As a requirement we want to take the request objects gzipped and response them using the same compression. How can I do this? I couldn't find any document describing this issue. How can I develop a wcf soap service that works like that and how to consume this kind of services? 回答1: Microsoft has a sample that demonstrates this (you can compile their code, and simply plug it into your application) GZip Encoder Sample There is a more

Json compression for transfer

由 被刻印的时光 ゝ 提交于 2020-01-04 04:15:30
问题 I was wondering what the current state of javascript based json compression is. Are there any libraries currently available that allow compressing json, either by replacing long names with single characters, or some other method? 回答1: Someone has implemented HPack in Javascript, which could really improve JSON data set sizes, assuming your data set is homogeneous. Since your emphasis is on transfer, rather than storage, don't forget to use things like gzip and to minimise your JSON. Those

Cannot decompress ZLIB/DEFLATE data

由 ╄→гoц情女王★ 提交于 2020-01-03 19:04:13
问题 I'm trying to extract data from compressed bytes from network capture file (PCAP.) Data from some of these packets don't have ZLIB header (the first 2 bytes, where lower 4 bits of first byte is always 8) and hence gave exception when I tried to decompress it using ZlibStream . Data with headers seem to work fine. As I understand that ZLIB is just a header and footer over DEFLATE, I pass these data without headers to DeflateStream . This time DeflateStream doesn't throw any error, it just gave
