reswqa opened a new pull request, #19530:
URL: https://github.com/apache/doris/pull/19530
# Proposed changes
Issue Number: close #19477.
## Problem summary
We can support this by add a new properties for tvf, like :
`select * from hdfs("uri" = "xxx", ..., "compress_type" = "lz4", ...)`
User can:
Specify compression explicitly by setting `"compression" = "xxx"`.
Doris can infer the compression type by the suffix of file name(e.g.
`file1.gz`)
Currently, we only support reading compress file in `csv` format, and on BE
side, we already support.
All need to do is to analyze the `"compress_type"` on FE side and pass it to
BE.
