Druid-Tranquility中查询粒度设置为5分钟
背景
我们知道可以通过tranquility从kafka读取数据写入druid做聚合，通过指定queryGranularity来指定查询的粒度。
"granularitySpec" : {
"type" : "uniform",
"segmentGranularity" : "hour",
"queryGranularity" : "hour",
"intervals" : ["2018-06-29T09/2018-06-29T13"]
}
Tranquility修改查询粒度
业务之前的查询需求都是小时粒度，现在要去能支持5min,10min粒度，了解到在druid中查询时间粒度可以设置为MINUTE、HOURE、FILVE_MINUTE等，但在tranquility设置查询粒度为5分钟，启动后报错，错误信息如下

2019-04-03 11:06:08,485 - [ERROR] - from com.metamx.tranquility.kafka.KafkaConsumer in KafkaConsumer-1
问题原因
在 tranquility 的最新版本(0.8.2)中 引用的druid为0.9.0，0.9.0的druid不支持查询粒度设置为5分钟.
github代码 里不支持5min
private static enum MillisIn
{
SECOND ( 1000),
MINUTE ( 60 * 1000),
FIFTEEN_MINUTE (15 * 60 * 1000),
THIRTY_MINUTE (30 * 60 * 1000),
HOUR ( 3600 * 1000),
DAY (24 * 3600 * 1000);
private final long millis;
MillisIn(final long millis) { this.millis = millis; }
}
解决方法
下载druid 0.9.0源代码，修改代码文件(https://github.com/apache/incubator-druid/blob/0.9.0/processing/src/main/java/io/druid/granularity/QueryGranularity.java), 在MillisIn中加入FIVE_MINUTE，修改之后
private static enum MillisIn
{
SECOND ( 1000),
MINUTE ( 60 * 1000),
FIVE_MINUTE (5 * 60 * 1000),
TEN_MINUTE (10 * 60 * 1000),
FIFTEEN_MINUTE (15 * 60 * 1000),
THIRTY_MINUTE (30 * 60 * 1000),
HOUR ( 3600 * 1000),
DAY (24 * 3600 * 1000);
private final long millis;
MillisIn(final long millis) { this.millis = millis; }
}
之后build代码文件，替换io.druid.druid-processing-0.9.0.jar
