Subject: [PATCH v6 0/3] reftable/stack: use geometric table compaction
Date: Mon, 08 Apr 2024 16:16:52 +0000 [thread overview]
Message-ID: <pull.1683.v6.git.1712593016.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1683.v5.git.1712255369.gitgitgadget@gmail.com>
Hello again,
This is the sixth version my patch series that refactors the reftable
compaction strategy to instead follow a geometric sequence. Changes compared
to v5:
* Reworded commit message to more clearly explain that the already existing
configuration to disable auto-compaction is being exposed to callers of
the library.
* Simplified expression to set the disable_auto_compact configuration.
Thanks for taking a look!

## Commit message ##
- reftable/stack: allow disabling of auto-compaction
+ reftable/stack: expose option to disable auto-compaction
+
+ The reftable stack already has a variable to configure whether or not to
+ run auto-compaction, but it is inaccessible to users of the library.
+ There exist use cases where a caller may want to have more control over
+ auto-compaction.
Move the `disable_auto_compact` option into `reftable_write_options` to
- allow a stack to be configured with auto-compaction disabled. In a
- subsequent commit, this is used to disable auto-compaction when a
- specific environment variable is set.
+ allow external callers to disable auto-compaction. This will be used in
+ a subsequent commit.
