 - `syncBatchSize`: The maximum number of documents fetched per batch during the initial sync from RxDB into TanStack DB (default: 1000). Larger values reduce round trips but use more memory; smaller values are lighter but may increase query calls. Note that this only affects the initial sync.

+Usually not, at least for TanStack DB queries themselves. TanStack DB queries run entirely in memory, so RxDB schema indexes do not affect the performance of TanStack DB's live queries. However, RxDB indexes may still be important if:
 - You run queries directly against RxDB (e.g. `rxCollection.find(...)`).
 - Your replication setup uses filtered queries or selectors.
 - You rely on RxDB to selectively load subsets of data instead of hydrating everything into memory.
