As discussed earlier, DPP is implemented based on the above-mentioned partition pruning and Broadcast hashing. Star-schema tables are broadly classified into Fact and dimension tables, mostly where the dimension table is much smaller compared to the fact table. When joining these tables, DPP creates an internal … See more It works based on the PushDownPredicateproperty. Using this, Spark can read the partitions only that are needed for the … See more When one of your join tables is smaller, Spark itself opts for BHJ (only if threshold memory is under the limit provided).

WebIn Dynamic hashing, the data buckets expand or shrink ( data buckets added or removed) dynamically according to the increase or decrease in records. It is also known as Extended hashing. Example. In this, hash functions are made to generate a large number of values. For example, three records A1, A2, and A3 need to be stored in the table. WebDynamic hashing [131 and extendible hashing 181 belong to this class. In this paper, we design a new dynamic hash function belonging to the second class. The storage utilization exceeds 69% and the auxiliary table, which modifies the hash functions, is re- lative smaller. The main idea is to apply the
