Dear Distinguished Colleagues: I need to add full-text search and somewhat free form queries to my application. Our data is made up of "items" that are stored in a single column family, and we have a bunch of secondary indices for look ups. An item has header fields and data fields, and the st

incremental backups not completely working?

Today I configured incremental backups in a test node which already has some data on it, and I found that backups are not created for STTables created by a compact: mddione@life:~/src/works/orange/Cassandra$ sudo find /var/lib/cassandra/data/one_cf /var/lib/cassandra/data/one_cf /var/lib/cas

Some one did search on Lucene, but for very fresh data they build search index in memory so data become available for search without delays. On 3 September 2012 22:25, Oleg Dulin wrote: > Dear Distinguished Colleagues: > >

Re: incremental backups not completely working?

2012-09-03 Thread Tyler Hobbs
Incremental backups are only triggered when new data is written to disk, such as a memtable being flushed or data being streamed in from a repair or move. Compaction does not create any new data, so there's no need to back up the result. On Mon, Sep 3, 2012 at 8:45 AM, wrote: > > Today I conf
