I'm attempting to install Nextcloud on MariaDB 10.4.11-MariaDB-1:10.4.11+maria~bionic in a docker container (mariadb:latest sha256:2f11cf2ec18988aec8346a5cf528d69ac3f0f4fc02af79ba28f4fd47b7778d6f).
First thing the installer does is attempt to create a table with ROW_FORMAT=COMPRESSED
in the DDL, which produces an error 140 "Wrong create options".
If I omit the row_format parameter, the table gets created, but with the DYNAMIC row_format.
What's going on here? Did ROW_FORMAT=COMPRESSED
get deleted at some point, or is the version of MariaDB docker is pulling not compiled with it in?
Short of modifying Nextcloud's SQL DDLs, what can I do here?
Edit:
Finally in a position to add more info about my system, here goes:
First, my my.cnf
[mysqld]
innodb_large_prefix=on
innodb_file_per_table=on
innodb_doublewrite=off
innodb_page_size=64k
innodb_file_format=barracuda
innodb_compression_algorithm=lz4
innodb_compression_default=ON
This results in a startup that contains lines:

Since I had to alter the create table DDL to even run, this is an example of one such table that actually got created:
CREATE TABLE `oc_users` (
`uid` varchar(64) COLLATE utf8mb4_bin NOT NULL DEFAULT '',
`displayname` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
`password` varchar(255) COLLATE utf8mb4_bin NOT NULL DEFAULT '',
`uid_lower` varchar(64) COLLATE utf8mb4_bin DEFAULT '',
PRIMARY KEY (`uid`),
KEY `user_uid_lower` (`uid_lower`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin `PAGE_COMPRESSED`='ON'
Note that only PAGE_COMPRESSED
was a valid option, the ROW_FORMAT=COMPRESSED
option just fails regardless.
The SHOW GLOBAL STATUS
command: https://pastebin.com/LzjsAvAX
And the SHOW VARIABLES
command: https://pastebin.com/64zpmh2Z
The system I'm running on has 8 GB of RAM, of which MariaDB is using approx 170 MB.

If someone else stumbles across this thread (like me) looking for a solution to a
or similar error from the mariadb for nextcloud, occurring whenever nextcloud tries to write to the DB: the important clue for me was, that this error might be related to an utf8 encoding issue. See here for the nextcloud documentation:
https://docs.nextcloud.com/server/21/admin_manual/configuration_database/mysql_4byte_support.html
TL;DR:
The solution from https://help.nextcloud.com/t/update-to-next-cloud-21-0-2-has-get-an-error/117028/7 for me was :
followed by
which will fix all tables so that writing to them becomes possible again.
