pg_dump_path 指向的pg_dump 备份文件 有什么要求?是 sql 还是二进制?文件后缀有没有要求?
我都试了,没效果,能提供pg_dump 的命令示例吗?
我是这样创建的备份文件:
pg_dump -h 10.168.4.91 -p 5321 -U postgres -W -F p -b -v -f "/opt/amazonriver/xzdssituation_p.sql" xzdssituation
这样配置的
"pg_dump_path": "/opt/amazonriver/xzdssituation_p.sql",
"subscribes": [{
"dump": true,
cannot work with new version pgx
INFO[0366] producer/leader/student_name_logs/0 state change to [normal]
ERRO[0366] write kafka msg err: kafka: Failed to deliver 2102 messages.
Please check if it works. Thank you.
运行环境:win10
数据库环境:pg 10.9.0
es版本:7.4
已经将pg_dump 配置到环境变量了
配置信息:

一段时间不更新的表(10分钟以上),第一次更新的数据没有被写入到到kafka中,第二次更新的才会写入kafka,出现问题频率较高
表必须设置主键,不然delete时无法同步,此时从pg订阅到的消息是空的,导致amazonriver无法删除。
能否支持的PG的wal物理文件方式的复制,不用逻辑方式,因为PG在用逻辑方式复制后,会出现主从延迟高的问题。
您好,我用amazonriver从PG同步到kafka,数据读取正常,但是未写入对应kafka的topic中,只是把数据打印到了终端,请问是不是我的配置或者操作存在问题:
kafka版本:0.10.2.0
postgresql版本:9.6.12
1.下载文件:amazonriver-linux-amd64.zip
2.解压后执行:./amazonriver -config kafka.conf
kafka.conf 文件配置信息如下:
{
"pg_dump_path": "",
"subscribes": [{
"dump": false,
"slotName": "slot_for_kafka",
"pgConnConf": {
"host": "192.168.216.87",
"port": 6432,
"database": "grabdb",
"user": "replica",
"password": "*****“
},
"rules": [
{
"table": "db40.dbm_monitor_timeliness",
"pks": ["table_name"],
"topic": "dbm_monitor_timeliness"
}
],
"kafkaConf": {
"addrs": ["192.168.200.94:9092"]
},
"retry": 0
}],
"prometheus_address": ":8080"
}
3.kafka的topic:dbm_monitor_timeliness信息如下
Topic:dbm_monitor_timeliness PartitionCount:1 ReplicationFactor:3 Configs:
Topic: dbm_monitor_timeliness Partition: 0 Leader: 3 Replicas: 3,2,1 Isr: 3,2,1
PGSQL 中执行TRUNCATE table test
报错

amazonriver:1.0.3

请问amazonriver能否实现高可用呢?如何实现?
运行amazonriver -config config.json报错如题,使用curl命令在es上面已经创建了对应的索引,es版本为5.5
这个问题必现,处理数据到32000多条的时候,后面的改动就监听不到了,逻辑复制WaitForReplicationMessage那里直接就接收不到表改动的waldata
