我有一个要求,因为redis流结构 specified length of data
我希望 transfer to influxDB in bulk
,但在传输过程中,批量插入的数据将与原始数据的顺序不同
数据生成代码的示例如下所示
try:
rs = redis.Redis(host="localhost", port=6379, db=0)
except Exception as e:
print(e)
count = 0
while(True):
Ts = int(round(time.time() * 1000))
count = count + 1
Count = count
data = {
"Ts": Ts,
"Count":Count
}
rs.xadd("simulation", data, maxlen=1000, approximate=False)
time.sleep(0.1)
数据读取和保存代码的示例如下所示
def parse(datas):
ts,data = datas
w_json = {
"measurement": 'test1',
"tags": {
'Ts': data[b'Ts'],
},
"fields": {
"Count":data[b'Count'].decode('utf-8'),
'Ts': data[b'Ts']
}
}
return w_json
try:
rs = redis.Redis(host="localhost", port=6379, db=0)
except Exception as e:
print(e)
client = InfluxDBClient(host="localhost", port=8086,database='test')
results = rs.xrange("simulation",count=1000)
influxdb_data = list(map(parse,results))
client.write_points(influxdb_data,batch_size=500)
print('insert success')
当我查看数据时,您会看到count数据顺序不是按该顺序输出的
> select Count,Ts from test1 limit 30;
name: sensor1
time Count Ts

有什么方法可以实现顺序批插入吗?
如果你能告诉我怎么解决的话,我会很感激的?
