I have a similar job as a technical support engineer, which requires a lot of DB querying as well. I've optimized a lot of my job by investigating the data through jupyter notebook, which is typically a data analyst / data scientist tool, but works really well for troubleshooting impact and behaviors through data. I highly recommend trying it out, it's made my work more seamless. Learned the job twice as fast as anyone of my other my peers; commended by my boss, in how surprised she found learned the material; seems to be a reoccurring event for my last three jobs.
