OpenTSDB-protector is good solution against OpenTSDB limitations. Its’ ideas can be used for other TSDBs out there.

In general, OpenTSDB has too many limitations comparing to more modern TSDB systems such as M3DB, InfluxDB or VictoriaMetrics:

• Low number for the maximum number of time series.
• Slow performance.
• High disk space usage.
• Increased hosting costs.

Did you consider switching to these systems in order to reduce pressure on these limitations?
