我正在做一个POC，我在其中使用Pheonix进行单次写入，以更新 数据库写入后。因此，我无法批量更新写入。我正进入（状态 每秒1个事务，作为TPS。我有3节点EMR集群。我在用 使用S3作为后端的HBase。
我尝试调整了在网上找到的参数，我创建了线程应用，但仍然 性能极其缓慢。
我已经编写了一个线程程序来将upsert数据批处理到Phoenix中。我是 使用Phoenix的原因在于二级索引功能。我变得非常 写性能慢。

HBase中使用的调整设置。问题是很难扩展，我尝试过
向Hbase群集添加更多节点，并且我还尝试向
客户端程序，但它的扩展速度不会超过每分钟6K，这是
非常慢。任何帮助是极大的赞赏。

HBASE IS INSTALLED ON EMR CLUSTER HERE TABLE IS CREATED USING ABOVE CREATE TABLE COMMANDS
EMR Cluster is 4 node m4.4xlarge cluster (32 vCore, 64 GiB memory, EBS only storage
EBS Storage:32 GiB)
Client is a Java program running in EC2 (m4.10xlarge m4.10xlarge 40 CPU 160 RAM 10 GiB Network EBS Only 10 Gbps 4,000 Mbps) Client is a multithreaded program that creates atomic connection to Hbase and performs inserts.

对于大写操作，我使用带有phoenix-spark的Spark作业，通过4个执行程序，我每秒可以达到16,000行向上插补。
计数查询非常慢是正常的，因为正如您的解释计划所示，它正在执行全扫描。这意味着它必须读取所有行才能获得实际计数。使用主键或至少以其开头查询数据时，Phoenix的功能非常强大。您给主键的开始越多，速度越快。
