Not sure where to begin? Getting Started
When i start reloading of core using dsetool command reindexing starts and run in background and we can check progress using core_reindexing_status option in dsetool.
But for some reasons, i want to find out starting time of reload operation and the total time taken by this operation is there any way to find this information?
dse version : 6.7.4
When you kick off the indexing command, it creates entries in the DSE logs indicating when it started and when it finished.
Here are sample log entries that shows when the reload was requested and when it completed:
INFO [mainIOThread-2] 2021-02-10 22:45:15,376 SolrCoreResourceManager.java:408 - Reloading core: contacts.users ... INFO [mainIOThread-2] 2021-02-10 22:45:15,812 AbstractSolrSecondaryIndex.java:308 - Getting initialization task for index 'contacts.users' in mode NORMAL with bootstrap state COMPLETED... INFO [mainIOThread-2] 2021-02-10 22:45:15,812 AbstractSolrSecondaryIndex.java:997 - Index 'contacts.users' initialized. Unblocking any pending invalidation...
If you specified reindex=true, log entries look like this:
INFO [mainIOThread-2] 2021-02-10 22:51:02,586 SolrCoreResourceManager.java:494 - Reindex core: contacts.users INFO [SolrSecondaryIndex contacts.users index reloader.] 2021-02-10 22:51:02,587 ReindexRequestsConsumer.java:50 - Will now run reindexing task 1 of Solr core contacts.users with deleteAll=true ... INFO [SolrSecondaryIndex contacts.users index reloader.] 2021-02-10 22:51:02,741 AbstractSolrSecondaryIndex.java:1630 - Finished reindexing Solr core 'contacts.users'. INFO [SolrSecondaryIndex contacts.users index reloader.] 2021-02-10 22:51:02,741 ReindexRequestsConsumer.java:55 - Completed reindexing task 1 of Solr core contacts.users
You should then be able to workout from the timestamps how long it took to reindex your data. Cheers!
