Dmemo v2 stopped showing some rows of a table, and dropped related tables (table_memo_raw_dataset* and masked_data). If you want to preserve the data of the tables, please take a backup of them before upgrading.
The tables are deleted if you run bin/docker_db_apply.sh with an environment variable RIDGEPOLE_DROP_TABLE=1. You should drop the tables after deploying dmemo v2.
Dmemo v2 also deprecates SynchronizeDataSources job. Please switch to ImportDataSourceDefinitions or SynchronizeDefinitions.
