Fix memory leak when using PebblesDB with small key-value pairs

[vijay03]

PebblesDB has a known memory-leak when used with a large number of small key-value pairs. This doesn't appear for some reason when PebblesDB is used with large key-value pairs (the default). This doesn't affect default behavior, but we would like to fix this going forward.

Hello, has this been fixed now? @vijay03

[vijay03]

No, not yet. I want to note that the problem doesn't appear for the default key-value pair sizes, so if you use those you will be fine.

default key-value pair sizes

hello, Is there any detail info about default key-value pair sizes ?

8 byte keys and 1024 byte values. The details are in the paper linked into the README.
