[jira] [Commented] (ARROW-11593) Parquet does not support wasm32-unknown-unknown target

    [ https://issues.apache.org/jira/browse/ARROW-11593?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17284005#comment-17284005 ] 

Dominik Moritz commented on ARROW-11593:
----------------------------------------

If lz4 is the issue, maybe we could switch to https://github.com/PSeitz/lz4_flex, which compiles to WASM.

> The Arrow crate successfully compiles to WebAssembly (e.g. https://github.com/domoritz/arrow-wasm) but the Parquet crate currently does not support the`wasm32-unknown-unknown` target. 
> Try out the repository at https://github.com/domoritz/parquet-wasm/commit/e877f9ad9c45c09f73d98fab2a8ad384a802b2e0. The problem seems to be in liblz4, even if I do not include lz4 in the feature flags.
