Description
*edit* added note: 8,192 split point limit does not apply to initial sharding of collection (added note here so the description of the ticket does not create mistaken impression that it does).
It would be good to revisit and clarify the manual on :
https://docs.mongodb.org/manual/reference/limits/#Sharding-Existing-Collection-Data-Size
We should improve the clarification on how the two sizes (256GB and 400GB) were calculated/estimated.
Also It would be great to revisit the table:
- Clarifying how the number of splits are calculated.
- Removing the 1MB chunk max collection size. As in the context of sharding an existing collection, generally it would be beneficial to increase the chunk size rather than reducing it.
NOTE: For 3.4, need to revisit this as there are limits for empty collections with hashed shard keys.
