Slow child dataset

Hello,

Currently, we are using multiple datamodels for same data (post filters are different). Now we are trying to merge them in single datamodel using child dataset to decrease disk space but appently there is massive performance impact on tstats search queries using child dataset.

In below example, while using child dataset Its almost 300+% increase in search time.

This might be expected as scaning full set of logs. Checking if there is any other way of using tstat query on child dataset to improve performace ?
