GROUP BY is a SQL command commonly used to aggregate the data to get insights from it. There are three phases when you group data: Split: the dataset is split up into chunks of rows based on the values of the variables we have chosen for the aggregation Apply: Compute an aggregate funct...

The data in the view is aggregated by 5-minute intervals. It can take several minutes for this data to appear in the table, so sys.resource_stats is more useful for historical analysis rather than near-real-time analysis. Query the sys.resource_stats view to see the recent history of a...
For example, the query can be run by a job that executes every minute on each primary database. If the difference between the last_commit_time of a primary database and any of its secondary databases has exceeded the recovery point objective (RPO) (for example, 5 minutes) since the last...

Filter for groups using COUNT() with GROUP BY and HAVING In example 4, we see that COUNT() can be used with GROUP BY. We can use the HAVING statement to filter for groups using the number of rows in that group. For example, to find the number of years that have less than 50 prod...
可以直接使用sqlline.py在服务端对HBase进行SQL操作。Phoenix的sqlline接口与开源社区保持一致,请参见http://phoenix.apache.org/。Sqlline常用语法见表1,常用函数见表2,命令行使用可以参考Phoenix命令行操作介绍章节。
