SOLR and Cassandra level two cache practice

amounted to $ billions of. In Newegg, tens of millions of users are browsing the goods every day, and they produce the following operations, such as trading orders. The data systems we build must cope with the increasing volume of data, robustness and reliability. At present, we use Cassandra to build Newegg's next generation online system. Cassandra is a distributed storage system without single point of failure, it has good concurrent write performance and random read performance, and mainly supports the data model of Key-value mode. In the practice of Newegg, many business scenarios require a two-level index, and the Cassandra of the two-level index does not meet the requirements; Cassandra cluster integration of the SOLR cluster model, the development team needs to maintain Cassandra and SOLR data synchronization, Read and write performance is reduced and development costs are high. To solve this problem, Newegg Big Data team developed the SOLR-based, Cassandra built-in two-level index.
