ARM architecture support

[DaviesX]

It seems like arm arch is not officially supported. Is it possible to build the extension from source on an arm platform?

I just "sucesfully" built this on the 64-bit version of raspibian on a raspberry pi 4. make ran sucesfully, but then the regression tests had 5 failures. link to gist with regression.diff and regression.out

EDIT: some of the errors are probably locale related. I recompiled and ran the test again with LC_ALL=C and now only one test fails (multi_extension). I have updated the gist with the new logs.

There is already a package available for citus 8 for postgres 11 on arm64:

pi@raspberry:~ $ apt info postgresql-11-citus
Package: postgresql-11-citus
Version: 8.0.0.PGDG-2
Priority: optional
Section: database
Source: citus
Maintainer: Citus Data <packaging@citusdata.com>
Installed-Size: 9850 kB
Depends: libc6 (>= 2.17), libcurl4 (>= 7.16.2), libpq5 (>= 9.2~beta3), postgresql-11
Homepage: https://github.com/citusdata/citus

APT-Sources: http://deb.debian.org/debian buster/main arm64 Packages
Description: sharding and distributed joins for PostgreSQL
 Citus is a distributed database implemented as a PostgreSQL extension. It
 provides functions to easily split a PostgreSQL table into shards to be
 placed on remote worker nodes. Citus can replicate shards, update their
 schemas, and keep track of shard health. An advanced distributed planner
 is included which handles queries and modifications against sharded tables.

I would be interested in getting docker images for linux/arm64v8 on dockerhuib similar to the linux/amd64 ones.

Currently I am running a Apple M1 computer and this issue resolution would be a big help!

Since there is no arm64/v8 architecture, I am using amd64 and running into performance issues as the computer has to interpret the amd64 instruction set which results in slower Citus runtime.

Thank you so much for reading and Citus is awesome! Love it so far!

HI @bartmika I have altered docker file from https://github.com/zalando/patroni/tree/master/kubernetes so it builds and runs on M1 airbook

Has anybody tried running it on Ampere ? It's a very affordable option these days.

Any updates or plans for brining ARM support to Citus? It looks like there used to be an ARM distribution but not anymore

merhaba, did you find any solution?
