> The strategy for online shard splitting is the same as that for normal (non SHARED shards.)
> During a split, the leader will forward updates to sub-shard leaders, those updates will
be buffered by the transaction log while the split is in progress, and then the buffered updates
are replayed.
> One change that was added was to push the local index to blob store after buffered updates
are applied (but before it is marked as ACTIVE):
> See https://github.com/apache/lucene-solr/commit/fe17c813f5fe6773c0527f639b9e5c598b98c7d4#diff-081b7c2242d674bb175b41b6afc21663
> This issue is about adding tests and ensuring that online shard splitting (while updates
are flowing) works reliably.
