Abstract

The equivalence connection between tables in the statistical analysis of data is one of the commonly used operations, but the price is relatively high. In big data environment, the connection of large scale data tables is less efficient. In order to solve this problem, this paper proposed a method for optimization of two-table equivalent connection process based on Spark. First, it constructed the Bloom filter to complete the filtering operation according to the low density of data density. Secondly, it combined the advantages of simi-join method and partition join methods, and used the greedy algorithm splitting methods for the filtered unilateral table. Lastly, it joined the split subsets, so it changed the connection process of two big tables into two stages of the two small table connection. Cost analysis and experiments show that the proposed algorithm improve performance compared with the existing Spark-based connection operation performance and data tilt.
