Common Library
Library for commonly used or shared code. Used by Aerospike Server and Aerospike C Client.
$ make clean
$ make
I would like to package this internally, but without an actual version I'd be guessing at what it is (for dependency purposes with different versions of the other clients). Are there any internal markers for this common library/repo version is? Or should I just make it the same as the C client.
Hello,
as_hashmap's set function maps the hash of a key to it's value. This is fine for numeric values, however, there would be collisions for string values, resulting in lost data.
For example,
as_val k1, v1;
as_val k2, v2;
/* .. init k1 & k2 as strings of unique uuids .. */
as_hashmap x;
/* .. init x .. */
as_hashmap_set(&x, &k1, &v1); /* (1) */
as_hashmap_set(&x, &k2, &v2); /* (2) */Assuming the hash code function for k1 and k2 return the same /hash/ value, as_hashmap_set will, internally, remove the mapping for k1, even though it has a unique /value/, to make room for k2.
Is this condition, especially for UDFs that produce maps with string keys as result, handled elsewhere or is this an actual issue?
Thanks,
Aaloan
