[IOTDB-4520] The tag schema region is implemented and supports the influxdb protocol

Open KeeProMise opened this issue 3 years ago • 0 comments

Description

The current influxdb adapter uses iotdb to store the order of tags in order to generate a unique path for the combination of tags with the same semantics during implementation. In this way, in the implementation, it is necessary to first access iotdb to obtain the order of tags, and then convert the tags into paths and generate PhysicalPlan, which results in poor performance and is more complicated to implement a tag model adapter. This work enables the influxdb adapter to support the use of native tag model metadata management modules.
