# Titan configuration sample: Cassandra over a socket | |
# | |
# This file connects to a Cassandra daemon running on localhost via | |
# Thrift. Cassandra must already be started before starting Titan | |
# with this file. | |
gremlin.graph=com.thinkaurelius.titan.core.TitanFactory | |
# The primary persistence provider used by Titan. This is required. It | |
# should be set one of Titan's built-in shorthand names for its standard | |
# storage backends (shorthands: berkeleyje, cassandrathrift, cassandra, | |
# astyanax, embeddedcassandra, hbase, inmemory) or to the full package and | |
# classname of a custom/third-party StoreManager implementation. | |
# | |
# Default: (no default value) | |
# Data Type: String | |
# Mutability: LOCAL | |
storage.backend=cassandrathrift | |
# The name of Titan's keyspace. It will be created if it does not exist. | |
# | |
# Default: titan | |
# Data Type: String | |
# Mutability: LOCAL | |
storage.cassandra.keyspace=titanserver | |
# The hostname or comma-separated list of hostnames of storage backend | |
# servers. This is only applicable to some storage backends, such as | |
# cassandra and hbase. | |
# | |
# Default: 127.0.0.1 | |
# Data Type: class java.lang.String[] | |
# Mutability: LOCAL | |
storage.hostname=127.0.0.1 | |
# Whether to enable Titan's database-level cache, which is shared across | |
# all transactions. Enabling this option speeds up traversals by holding | |
# hot graph elements in memory, but also increases the likelihood of | |
# reading stale data. Disabling it forces each transaction to | |
# independently fetch graph elements from storage before reading/writing | |
# them. | |
# | |
# Default: false | |
# Data Type: Boolean | |
# Mutability: MASKABLE | |
cache.db-cache = true | |
# How long, in milliseconds, database-level cache will keep entries after | |
# flushing them. This option is only useful on distributed storage | |
# backends that are capable of acknowledging writes without necessarily | |
# making them immediately visible. | |
# | |
# Default: 50 | |
# Data Type: Integer | |
# Mutability: GLOBAL_OFFLINE | |
# | |
# Settings with mutability GLOBAL_OFFLINE are centrally managed in Titan's | |
# storage backend. After starting the database for the first time, this | |
# file's copy of this setting is ignored. Use Titan's Management System | |
# to read or modify this value after bootstrapping. | |
cache.db-cache-clean-wait = 20 | |
# Default expiration time, in milliseconds, for entries in the | |
# database-level cache. Entries are evicted when they reach this age even | |
# if the cache has room to spare. Set to 0 to disable expiration (cache | |
# entries live forever or until memory pressure triggers eviction when set | |
# to 0). | |
# | |
# Default: 10000 | |
# Data Type: Long | |
# Mutability: GLOBAL_OFFLINE | |
# | |
# Settings with mutability GLOBAL_OFFLINE are centrally managed in Titan's | |
# storage backend. After starting the database for the first time, this | |
# file's copy of this setting is ignored. Use Titan's Management System | |
# to read or modify this value after bootstrapping. | |
cache.db-cache-time = 180000 | |
# Size of Titan's database level cache. Values between 0 and 1 are | |
# interpreted as a percentage of VM heap, while larger values are | |
# interpreted as an absolute size in bytes. | |
# | |
# Default: 0.3 | |
# Data Type: Double | |
# Mutability: MASKABLE | |
cache.db-cache-size = 0.5 |
