Impending IndexedDB SQLite migration

[Hans]

Is there any information on the upcoming migration beyond what's referenced in this issue: https://issues.chromium.org/issues/40253999

Will there be any prep or code changes required? (guessing no)

When can we expect existing extension databases to begin to be migrated?

What are the migration triggers/gates?

Will there be an origin trial?

What's the timeline for the final removal of LevelDB dependencies?

My extension uses IndexedDB as the primary data store for free users. I'm concerned about potential data loss for those users who miss the migration window.

I'm also somewhat concerned about this quote: "As unused databases will never migrate, we can proactively evict older buckets (N months without access; 3 < N < 15)" in this doc. What does that mean for users who don't use the extension for a few months?

Thanks,

Hans

Judging by the source code findings eviction in general doesn't apply to extensions with unlimitedStorage permission, but a clarification for this case is indeed necessary.
