InMemoryTrie.SpaceExhaustedException (apache-cassandra API)

java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - org.apache.cassandra.db.tries.InMemoryTrie.SpaceExhaustedException

All Implemented Interfaces:

java.io.Serializable

Enclosing class:

InMemoryTrie<T>
```
public static class InMemoryTrie.SpaceExhaustedException
extends java.lang.Exception
```
Because we use buffers and 32-bit pointers, the trie cannot grow over 2GB of size. This exception is thrown if a trie operation needs it to grow over that limit. To avoid this problem, users should query InMemoryTrie.reachedAllocatedSizeThreshold() from time to time. If the call returns true, they should switch to a new trie (e.g. by flushing a memtable) as soon as possible. The threshold is configurable, and is set by default to 10% under the 2GB limit to give ample time for the switch to happen.
