hi Team, I have question about es, mysql is es used for searching in datahub? if es is used for searching in datahub then what happens if i delete all indices in elasticsearch and keep mysql ? Is there any logic in datahub to make sync right between elasticsearch and mysql? Thanks

If you delete all the indices then you get nothing when you search. Also lose all your profiling data. There is a reindexing job to sync between MySQL and es that you can run manually.

Thanks how can i run that sync job manually??

Depends on your deployment. There is a datahub upgrade image inside docker/datahub-upgrade

ok so after i delete all indices, all i need to restore search feature is run datahub-upgrade again?? how do i pass argument to datahub-upgrade to only restore search indices? and which index in elasticsearch keeps search information??

i just run

./datahub-upgrade.sh -u RestoreIndices

ok thanks for help
