Terracotta Client Properties
Client configuration properties typically address the behavior, size, and functionality of in-memory data stores. Others affect certain types of cache-related bulk operations.
See also How Server Settings Can Override Client Settings.
Properties are set in ehcache.xml except as noted.
General Settings
The following default settings affect in-memory data.
Property
Default Value
Notes
value mode
SERIALIZATION
consistency
EVENTUAL
XA
false
orphan eviction
true
local key cache
false
synchronous writes
false
ttl
0
0 means never expire.
tti
0
0 means never expire.
transactional mode
off
persistence strategy
none
maxEntriesInCache
0
0 means that the cache will not undergo capacity eviction (but periodic and resource evictions are still allowed)
maxBytesLocalHeap
0
maxBytesLocalOffHeap
0
maxEntriesLocalHeap
0
0 means infinite.
NonStop Cache
The following default settings affect the behavior of the cache when while the client is disconnected from the cluster. For more information on these settings, see Configuring Nonstop Cache.
Property
Default Value
Notes
enable
false
timeout behavior
exception
timeout
30000ms
net.sf.ehcache.nonstop
bulkOpsTimeoutMultiply
Factor
10
This value is a timeout multiplication factor affecting bulk operations such as removeAll() and getAll(). Since the default nonstop timeout is 30 seconds, it sets a timeout of 300 seconds for those operations. The default can be changed programmatically:
cache.getTerracottaConfiguration()
.getNonstopConfiguration()
.setBulkOpsTimeoutMultiplyFactor(10)
Bulk Operations
The following properties are shown with default values. These properties can be set to custom values using Terracotta Server Array Properties.
Increasing batch sizes may improve throughput, but could raise latency due to the load on resources from processing larger blocks of data.
Property
Default Value
Notes
ehcache.bulkOps.maxKBSize
1MB
Batch size for bulk operations such as putAll and removeAll.
ehcache.getAll.batchSize
1000
The number of elements per batch in a getAll operation.
ehcache.incoherent.putsBatch
ByteSize
5MB
For bulk-loading mode. The minimum size of a batch in a bulk-load operation. Increasing batch sizes may improve throughput, but could raise latency due to the load on resources from processing larger blocks of data.
ehcache.incoherent.putsBatch
TimeInMillis
600 ms
For bulk-loading mode. The maximum time the bulk-load operation takes to batch puts before flushing to the Terracotta Server Array.
