--- Comment #2 from [email protected] --- Thank you for the quick reply, Howard. You are talking about a limit on the number of dirty pages. Do you know the limit? I looked at this part of the code [1] as the `mt_dirty_room` is assigned `MDB_IDL_UM_MAX`. I tried to compute the value of it, and it seems that only 65535 pages can be dirty in a single transaction. Is that right? And what do you mean by "in memory"? Are the dirty pages stored in RESident memory? It would mean that LMDB can allocate up to ~256 MiB (65535*4*1024 Bytes) or ~1 GiB when pages are 16 KiB. If everything I say above is correct: - Can we increase that limit? - Can we move the dirty pages to disk? - Can we track this number? - Can you tell me how much LMDB can allocate in RES? Is there a known limit?
