在多处理脚本中使用elasticsearch-py的正确方法是什么?我应该在启动进程之前创建一个新的客户端对象并使用该对象,还是应该在每个进程中创建一个新对象。第二个给出了一个关于elasticsearch
的连接问题的错误由于 基兰
答案 0 :(得分:0)
答案 1 :(得分:0)
当我将客户端对象声明为全局变量时,似乎第一种方法对我有用。
from multiprocessing import Pool
from elasticsearch import Elasticsearch
import time
def task(body):
result = es.index(index='test', doc_type='test', body=body)
return result
def main():
pool = Pool(processes=MAX_CONNECTS)
result = []
for x in range(10):
result.append(pool.apply_async(task, ({'id': x},)))
time.sleep(1)
for rs in result:
print(rs.get())
if __name__ == "__main__":
MAX_CONNECTS = 5
es = Elasticsearch(hosts="localhost", maxsize=MAX_CONNECTS)
main()
输出看起来像
