(read-only slaves) From: Jacques To: dev@hbase.apache.org, lars hofhansl Content-Type: multipart/alternative; boundary=f46d043c08d866a3a204b78b8a75 X-Virus-Checked: Checked by ClamAV on apache.org --f46d043c08d866a3a204b78b8a75 Content-Type: text/plain; charset=ISO-8859-1 Thanks for the pointer to HBASE-2196. My use case is more to minimize downtime (better to serve stale data than to wait for region transition). I was just curious if anyone had started putting code to disk on the HBASE-2357.
