Find the index by taking the modulo (hash code% array_size). hashfn () does this. Call the getIndexWithinBucket () function for that index.
WebThey didn't seem to do much for me. However, if you want to do something similar for these hash tables, check out the example here. Code for the benchmarks can be found here. EDIT: I realized that gp_hash_table is the way to go, not cc_hash_table. gp_hash_table sacrifices ~10% reading/writing speed to gain 3-6x in insertion/deletion/clearing.

Hashing means using some function or algorithm to map object data to some representative integer value. This so-called hash code (or simply hash) can then be used as a way to narrow down our search when looking for the item in the map.
