Data Changes Logging
Hi All,
We got a peculiar requirement from client, not sure whether the SOLR supports it or not. We would like to have alerts in place if we have the changes on the particular column for more than specific threshold on said day.
For example: Say, we have column say "Name" on which we have say around 30% changes we would like an alert. I am not sure whether we have some logging mechanism to get this done. Any ideas would be appreciated.
Thanks and Regards,
Preeti

Do a range search on that field with the desired date range. Request rows=0. Compare the numFound to the total docs.

Preeti,
Suppose you have a field named 'modifiedDate' and you update it when you change the 'column' (i assume you mean some field in your document). Then you need to decide how often to check for alerts. When you check for an alert you would do a select with a bit of date math to see how many of your documents have a recent modifiedDate. I am leaving out the details.
Cheers -- Rick
