The anticipated gzip support was recently released in 2018.2, I finally got some time to get started with some of OS Mastermap data stored as gz with gml inside.
Unfortunately, I got the following message when I tried to open the gz file.
"error extracting file: unable to read file meta data"
I guess it might have something to do with the fact that gz read only support limited file format, although gml is supported if it is not gzipped. (as I shared in https://community.alteryx.com/t5/Alteryx-Designer-Ideas/Support-for-GZIP-gz-compressed-files-in-input-tool-both-in/idc-p/176758#M6819 )
Just want to bring this issue to the attention of the developers and the community, in case someone might have a similar problem, or may have time and may be able to provide some signpost.
One workaround I can think of is to unzip the gz file into temporary files (I have over a thousand, would not be a problem for batch macro), and then use the existing gml capactiy. But as a lazy user, who is a little scared and short of time to use the run command tool, as introduced here: https://tarsolutions.co.uk/blog/unzip-a-file-in-alteryx/ . Just to check if supporting gml will be soon released in beta version, I am happy to help test it out.
Many thanks
Steven
