单个表约5个字段，每个事务insert单条数据，分别同步到es与kafka，在没有wal积压的情况下，测试峰值tps 53 | 54 | ## ES 55 | 56 | 1. 单事务单表同步，app cpu ≈ 20.08%，load 峰值1.03，mem ≈ 700MB；内网 net/io in ≈ 154.95Mb，net/io out ≈ 23.32Mb，ES先出现瓶颈； 57 | 2. 压测端压力峰值约 17k/s，DB tps ≈ 18k，es avg rate index ≈ 13k/s； 58 | 3. 单事务多表同步，app cpu、es index rate不会明显提升； 59 | 4. 补充4c8g服务器的资源消耗对比：cpu ≈ 28.86%，load峰值0.6，mem ≈ 48MB；内网 net/io in ≈ 114.77Mb，net/io out ≈ 18.7Mb。 60 | 61 | ## kafka 62 | 63 | 1. 单事务单表同步，cpu ≈ 28.15%，load 峰值0.4，mem ≈ 30MB；内网 net/io in ≈ 253.66Mb，net/io out ≈ 28.53Mb；压测端压力峰值约 23k/s，DB tps ≈ 23k，kafka rate ≈ 23k； 64 | 2. 单事务多表同步，cpu ≈ 35.38%，load 峰值0.09，mem ≈ 30MB；内网 net/io in ≈ 292.71Mb，net/io out ≈ 37.99Mb；压测端压力峰值约 21k/s，DB tps ≈ 40k，kafka rate ≈ 40k； 65 | 综述 66 | 1. 应用会过滤 slot配置的数据库内所有表的DML操作，消耗cpu ≈ 17%； 67 | 2. es 同步速率远逊于kafka 同步速率，前提是 应用服务器和DB服务没有瓶颈。在我们的测试环境，受限于基础配置，只能体现es和kafka部分性能差异； 68 | 3. 当日志级别为error时，同步过程中服务器的cpu、mem、net io消耗均比较低，mem占用取决于wal堆积的大小； 69 | 70 |
