We have a > large number ( ~ 40,000 ) of clients hitting this cluster. Client normally > connects to 4 cassandra instances. Some event (we think it is a schema change > on server side) triggered the client to establish connections to all > cassandra instances of local DC. This brought the server to its knees. The > client connections failed and client attempted re-connections. > Cassandra should protect itself from such attack from client. Do we have any > knobs to control the number of max connections? If not, we need to add that > knob. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
