According the docs, the hash table is restricted to a maximum size of 2^16 (65536)
buckets.
This doesn't mean that the htable can only hold 65k entries, just that it's the
maximum number of unique buckets. Assuming a theoretically ideal distribution where every
value has a unique bucket, after 65k values, you will get collisions. Collision chains
attached to buckets are linear lists. After collision chains get deep, performance becomes
more and more linear.
So, you can put 2m values into the htable. I am not sure that it is the optimal use of an
htable, however.

*Asunto:* Hash Table capacity
Hello list.
I have a question about the HTABLE module. Suppose that I have a mysql
database with 2 million of records. Is possible to load this table as
a
hash table compatible with Kamailio!?
Hope someone can help me.
Thanks,
Ricardo Martinez.-
