解析kafka的mysql binlog问题
你好。这个是我的解析sql。我想读取binlog的 data数据和table 数据。 为什么可以取到table 不能取到data呢？
private static final String KAFKA_SQL = "CREATE TABLE kafkaTable (\n" +
" `data` VARCHAR , " +
" `table` VARCHAR " +
") WITH (" +
" 'connector' = 'kafka'," +
" 'topic' = 'order_source'," +
" 'properties.bootstrap.servers' = '***'," +
" 'properties.group.id' = 'real1'," +
" 'format' = 'json'," +
" 'scan.startup.mode' = 'earliest-offset'" +
")";
具体见附件 有打印

Hi，
附近应该是收不到的，包括图片啥的
只能回复纯文本，贴代码，如果真的需要图片的话，可以上传到其他的网站上，然后给个连接跳转过去

直接转成string1.11版本还不支持，会在1.12修复，参考jira[1]

你好 收到。谢谢。 因为这个topic 是有很多表的binlog的。所以解析成array 也是不行的。长度和字段都不一致
另外想请教下 1.11 版本 datastream 可以转换为 blink的table吗。 看到例子 好像都是 useOldPlanner 来转的，
但是我想用blink 写入到hive。 我这边需求 就是通过binlog - flink - hive。 不同的mysql表写入到不同hive表。

因为 "data" 是一个复杂结构，不是单纯的 string 结构。所以1.11为止，这个功能还不支持。
1.12 中已经支持读取复杂结构为 string 类型了。

Re:Re: 解析kafka的mysql binlog问题
Posted by air23 <wa...@163.com>.
你好。
我猜测 是有可能是这个问题。但是我这个topic是 读取的一个库的binlog。有很多表 所以ARRAY<ROW< op_id STRING, order_id STRING>>
这种 里面 不是固定的
所以我想用datastream 解析 然后在根据表不同 解析成不同的table。但是发现blinkplaner 好像不可以datastream 转换为table。或者是我没有发现这个例子
谢谢

Re:Re: 解析kafka的mysql binlog问题
Posted by air23 <wa...@163.com>.
你好 测试代码如下
private static final String KAFKA_SQL = "CREATE TABLE kafkaTable (\n" +
" `data` VARCHAR , " +
" `table` VARCHAR " +
") WITH (" +
" 'connector' = 'kafka'," +
" 'topic' = 'source_databases'," +
" 'properties.bootstrap.servers' = '***'," +
" 'properties.group.id' = 'real1'," +
" 'format' = 'json'," +
" 'scan.startup.mode' = 'earliest-offset'" +
")";
public static void main(String[] args) throws Exception {
//bink table
StreamExecutionEnvironment bsEnv = StreamExecutionEnvironment.getExecutionEnvironment();
EnvironmentSettings bsSettings = EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build();
StreamTableEnvironment bsTableEnv = StreamTableEnvironment.create(bsEnv, bsSettings);
TableResult tableResult = bsTableEnv.executeSql(KAFKA_SQL);
tableResult.print();
Table table = bsTableEnv.sqlQuery("select * from kafkaTable");
bsTableEnv.toAppendStream(table, Row.class).print().setParallelism(1);
bsEnv.execute("aa");
}
输出结果如下 data都是空的。数据格式为canal解析的mysql binlog
,order_operation_time
,inventory_batch_log
,order_log
,order_address_book
,product_inventory
,order_physical_relation
,bil_business_attach
,picking_detail
,picking_detail
,orders
另外再问个问题。1.11版本 blink 不能datastream转table吗？
看到例子都是useOldPlanner 来转table的。
