报错如上，请教哪里好改一下吗？

不是开始后马上报错，而是写入了几条数据后才弹出报错，后台写入也同时停止了

请检查一下ask_price的数据类型

几个数据库都试了一下，就influx出现这个问题，目前接口应该不支持influx2.0是吗？
另外想请教一下，如果要进行长时间的全市场行情录制，几百个contracts保存全部tick信息的话，哪种数据库要好一些？

可以考虑clickhouse

谢谢，我的意思是在现有的influx mongo postgresql mysql里，如果要选一个哪个更好一些，对数据量可以限制，硬件配置也不太高

influxdb

谢谢，有支持influxdb 2.0的计划吗？
