default key generator spring

DefaultKeyGenerator (Spring Framework 4.0.9.RELEASE API)

Default key generator. Returns 0 if no parameters are provided, the parameter itself if only one is given or a hash code computed from all given parameters' hash code values. Uses the constant value 53 for any null parameters given.. NOTE: As this implementation returns only a hash of the parameters it is possible for key collisions to occur.

Spring Default Cache Key Generation. How to generate

By default Spring uses a simple key generation based on the following algorithm: If @Cacheable method has no arguments then SimpleKey.EMPTY is used as key. If only one argument is used, then the argument instance is used as key. If more than one argument is used, then an instance of SimpleKey composed of all arguments is used as key.

Spring DefaultKeyGenerator gotcha – ethlo

However I had not paid too much attention to the parameters going into the cache key. I would have expected something like concatinated toString() or something similar, however the default is to use the hashCode() of each parameter and create another (32-bit) hash code. Obviously this can easily generate collisions as we shall soon see.

Why you should never use the TABLE identifier generator

Jan 04, 2017  Even if it cannot benefit from JDBC batching, the IDENTITY generator still manages to outperform the TABLE generator, which uses a pooled optimizer with an increment size of 100.. The more threads are used, the less efficient the table generator becomes. On the other hand, identity columns scale much better with more concurrent transactions.

Improve DefaultKeyGenerator [SPR-9036] Issue #13675

Jan 18, 2012  The underlying cache mechanism is a hashtable of some sort, so it will calculate the hash of the key anyway. But it will have a collision-resolution strategy, unlike the KeyGenerator. I suggest: concatenating the string representations of primitives, and the hashcode of non-primitives. adding the class name and method name to the key
