Slow storing of data for shefParser

使用附带的 shefit 文件复现 shefParser -i $FILE --loader cda[$CDA_API_ROOT][$CDA_API_KEY] --processed 命令，然后结合报告中的请求和 connection-pool traceback 检查 shef/loaders/cda_loader.py。如果有 Catalina 日志，请使用它们来确定存储缓慢和 500 响应的来源；当文件能够成功存储，并且相较于报告的运行时间有可测量的改进时，即视为完成。

We are utilizing shefParser to store data for a couple of our data acquisition processes as we prepare for cloud migration. Those processes either store shefit files to the database with cda, or store shef.e files to the database with cda. It seems to be significantly slower than processShefit was or our old direct-store methods.

For example, utilizing our MRRPPCS data stream, which uses a diode to send main stem data once an hour. For this process, shefParser ingests shefit files and stores them.

Each hour the 6 main stem projects send 14 values (for a total of approximately 84 values). The shefParser program takes on average 8 minutes to store these values.

An example shefit file is attached. Our bash script cycles through 6 shefit files (one for each project) and stores the data. It does this twice since the diode can send data to one of two folders depending on which machine is sending the data. Total runtime is generally 8 minutes to store these 12 files.

Argument used in the bash script:
shefParser -i $FILE --loader cda[$CDA_API_ROOT][$CDA_API_KEY] --processed

Error we see from the bash script log (specifically it seems worrisome to see the "too many 500 responses" and connection pool lines):

During handling of the above exception, another exception occurred:

We can try to get some additional information from the catalina logs if that's necessary.

When we have had missing data, the slowness of shefParser makes it unusable. We have had to revert back to processShefit when we had to backfill more than a few hours.
