Summary
In this chapter, you learned how to shard data. It was difficult (because the product is young) to cover all the aspects of Spider regarding performance and features in this chapter; however, if you want to go ahead, you have to look at Direct SQL (Map Reduce on remote backend) with UDF functions.
Spider is a newly introduced technology in MariaDB, and this chapter was an introduction to it. Spider covers a lot of missing aspects, but surely will evolve faster in the coming years (as it was recently introduced in MariaDB).
