symious opened a new pull request #3082: URL: https://github.com/apache/ozone/pull/3082
## What changes were proposed in this pull request? Recon stores the mapping of ContainerKeyPrefix in local RocksDB. When Recon is applying DELETE or UPDATE events from OM, it will run search the whole table for each to_be_deleted record. In a big cluster, the record count in this table could be very large, and the search loop for each records is very slow. In our cluster there are 90m records, each loop cost over 70 seconds, if a delta OM events have 100 DELETE or UPDATE events, it will took about two hours to apply these updates. This ticket is to accelerate the process with the help of a new local table. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-6312 ## How was this patch tested? unit test. -- This is an automated message from the Apache Git Service.
