+1 on cleaning obsolete indices from sever. This comes in handy in cases where users are trying to optimize indices and may try out different options. While the obsolete indices themselves do not cause any issues with CPU/Memory usage of Pinot servers, they may eat up disk storage that can be expensive, moreover, may prevent pushing of more data (experienced in certain deployments already). This can be achieved in multiple ways: - Re-download of segments from controller/deep-store, and then build the necessary indices as per the indexing config. - Let the servers themselves cleanup the indices (as part of reload) locally, without needing to download from controller. -- This is an automated message from the Apache Git Service.
