Performance Test

Target

The performance of ShardingSphere-JDBC, ShardingSphere-Proxy and MySQL would be compared here. INSERT & UPDATE & DELETE which regarded as a set of associated operation and SELECT which focus on sharding optimization are used to evaluate performance for the basic scenarios (single route, replica query & encrypt & sharding, full route). While another set of associated operation, INSERT & SELECT & DELETE, is used to evaluate performance for replica query. To achieve the result better, these tests are performed with jmeter which based on a certain amount of data with 20 concurrent threads for 30 minutes, and one MySQL has been deployed on one machine, while the scenario of MySQL used for comparison is deployed on one machine with one instance.

Test Scenarios

Single Route

On the basis of one thousand data volume, four databases that are deployed on the same machine and each contains 1024 tables with id used for database sharding and k used for table sharding are designed for this scenario, single route select sql statement is chosen here. While as a comparison, MySQL runs with INSERT & UPDATE & DELETE statement and single route select sql statement on the basis of one thousand data volume.

Replica Query

One primary database and one replica database, which are deployed on different machines, are designed for this scenario based on ten thousand data volume. While as a comparison, MySQL runs with INSERT & SELECT & DELETE sql statement on the basis of ten thousand data volume.

Replica Query & Encrypt & Sharding

On the basis of one thousand data volume, four databases that are deployed on different machines and each contains 1024 tables with id used for database sharding, k used for table sharding, c encrypted with aes and pad encrypted with md5 are designed for this scenario, single route select sql statement is chosen here. While as a comparison, MySQL runs with INSERT & UPDATE & DELETE statement and single route select sql statement on the basis of one thousand data volume.

Full Route

On the basis of one thousand data volume, four databases that are deployed on different machines and each contains one table are designed for this scenario, field id is used for database sharding and k is used for table sharding, full route select sql statement is chosen here. While as a comparison, MySQL runs with INSERT & UPDATE & DELETE statement and full route select sql statement on the basis of one thousand data volume.

Testing Environment

Table Structure of Database

The structure of table here refer to sbtest in sysbench

CREATE TABLE `tbl` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `k` int(11) NOT NULL DEFAULT 0,
  `c` char(120) NOT NULL DEFAULT '',
  `pad` char(60) NOT NULL DEFAULT '',
  PRIMARY KEY (`id`)
);

Test Scenarios Configuration

The same configurations are used for ShardingSphere-JDBC and ShardingSphere-Proxy, while MySQL with one database connected is designed for comparision. The details for these scenarios are shown as follows.

Test Result Verification

SQL Statement

INSERT+UPDATE+DELETE sql statements:
INSERT INTO tbl(k, c, pad) VALUES(1, '###-###-###', '###-###');
UPDATE tbl SET c='####-####-####', pad='####-####' WHERE id=?;
DELETE FROM tbl WHERE id=?

SELECT sql statement for full route:
SELECT max(id) FROM tbl WHERE id%4=1

SELECT sql statement for single route:
SELECT id, k FROM tbl ignore index(`PRIMARY`) WHERE id=1 AND k=1

INSERT+SELECT+DELETE sql statements：
INSERT INTO tbl1(k, c, pad) VALUES(1, '###-###-###', '###-###');
SELECT count(id) FROM tbl1;
SELECT max(id) FROM tbl1 ignore index(`PRIMARY`);
DELETE FROM tbl1 WHERE id=?
