hash table from pmdk

[Yue Li]

hello, 

Just wondering if there Is any implementation of hash table from PMDK that provides atomicity on pmem? 

Best, 

Yue

Hi Yue,

 

There is one in our examples:

                pmdk/src/examples/libpmemobj/hashmap

 

Actually, there are two variants of hashmap implementation - one that uses pmemobj transactions and another based on atomic (nont-transactional) APIs. See README for details. See also:

                pmdk/src/examples/libpmemobj/map

 

for a simple kv store example (server/client) based on this hash map implementation (and other data structures/trees/etc.).

 

It's just an example, but it pretty well illustrates how to implement your own hash table with libpmemobj.
