4.2
|
||||
* Add support to generate a One-Shot heap dump on unhandled exceptions (CASSANDRA-17795)
|
||||
* Rate-limit new client connection auth setup to avoid overwhelming bcrypt (CASSANDRA-17812)
|
||||
* DataOutputBuffer#scratchBuffer can use off-heap or on-heap memory as a means to control memory allocations (CASSANDRA-16471)
|
||||
* Add ability to read the TTLs and write times of the elements of a collection and/or UDT (CASSANDRA-8877)
