cts:before-query( $timestamp as xs:unsignedLong ) as cts:before-query
Summary
Returns a query matching fragments committed before or at a specified timestamp.
| Parameters | |
|---|---|
| timestamp | A commit timestamp. Database fragments committed before this timestamp are matched. |
Usage Notes
Fragment commit timestamps change not only by application transactions, but also by system transactions from the reindexer or the rebalancer. The query will also match fragments whose timestamps have been changed because of reindexing and rebalancing before the given timestamp.
Example
cts:uris("",(),
cts:before-query(xdmp:wallclock-to-timestamp(
fn:current-dateTime() - xs:dayTimeDuration("PT1H")))
)
=> URIs of fragments committed one hour before the current time
