Class ::acs::HashKeyPartitionedCache

::acs::HashKeyPartitionedCache create ... \
           [ -default_size (default "100KB") ] \
           [ -maxentry:integer maxentry:integer ] \
           [ -name name ] \
           [ -package_key:required package_key:required ] \
           [ -parameter:required parameter:required ] \
           [ -partitions:integer (default "2") ] \
           [ -timeout (default "5m") ]

Partitioned cache, where the partition numbers are computed via a hash function. Key-partitioning is based on a modulo function using a special partition_key, which has to be numeric

Defined in packages/acs-tcl/tcl/acs-cache-procs.tcl

Class Relations

• class: ::nx::Class
• superclass: ::acs::KeyPartitionedCache

::nx::Class create ::acs::HashKeyPartitionedCache \

Methods (to be applied on instances)

• flush_pattern (scripted, public)

   <instance of acs::HashKeyPartitionedCache> flush_pattern \
      -partition_key partition_key  pattern

  flush just in all partitions

  Switches:

  -partition_key (required)

  Parameters:

  pattern (required)

  Testcases:

  No testcase defined.

  :flush_pattern_in_all_partitions $pattern

• set (scripted, public)

   <instance of acs::HashKeyPartitionedCache> set \
      -partition_key partition_key  key value

  Set a single value in the cache. It transforms the partition key into a hash value. This code uses ns_cache_eval to achieve this behavior, which is typically an AOLserver idiom and should be avoided.

  Switches:

  -partition_key (required)

  Parameters:

  key (required)

  value (required)

  Testcases:

  No testcase defined.

  next [list -partition_key [ns_hash $partition_key] $pattern]
