Most commonly +used record index is the HoodieBloomIndex. For larger installations and for global index types, performance might be an issue +due to loading of bloom from large number of data files and due to throttling issues with some of the cloud stores. We are proposing to +build a new Metadata index (metadata table based bloom index) to boost the performance of existing bloom index. Review comment: Why not use a record-level-index for this functionality? Is it because of storage requirements? Wouldn't a record level index be faster than using a bloom based index? -- This is an automated message from the Apache Git Service.
