The UPDATE EXTENSIONS
statement allows to sychronize the local installed extension state with the repository that published a given extension.
This statement is the recommended way to keep up to date with new feature or bug fixed being rolled out by extension developers.
Updating All Extensions
Say you want to automatically check for updates for all extensions (for the current DuckDB version and platform) currently installed in the extension_directory
.
UPDATE EXTENSIONS;
This will iterate over the extensions, and inform user on which ones have been bumped.
UPDATE EXTENSIONS
will use the information about where a given extension has been sourced, and try to fetch it only from there.
Updating Selected Extensions
You can provide a list of extension names to be updated. This allow more fine grained control:
UPDATE EXTENSIONS (name_a, name_b, name_c);
How It Works
UPDATE EXTENSIONS
is implemented by storing, if available, the ETag information, and sending a GET request conditional on the fact that the remote extension is different (using the ETag as proxy) than the local available one. This ensures that UPDATE EXTENSIONS
on consecutive instructions (if the remote state has not changed) is rather inexpensive.
If a change is found for a given extension, DuckDB performs the following operation. For example, if name_a
and name_c
changed, then:
UPDATE EXTENSIONS (name_a, name_b, name_c);
will result in the following commands:
FORCE INSTALL name_a;
FORCE INSTALL name_c;
