GraphDatabaseConfiguration (JanusGraph-Core: Core Library for JanusGraph 1.1.0-20240305-121359.1b26e03 API)

java.lang.Object
- org.janusgraph.graphdb.configuration.GraphDatabaseConfiguration

```
public class GraphDatabaseConfiguration
extends Object
```
Provides functionality to configure a JanusGraph INSTANCE.

A graph database configuration is uniquely associated with a graph database and must not be used for multiple databases.
After a graph database has been initialized with respect to a configuration, some parameters of graph database configuration may no longer be modifiable.

```
  - DB_CACHE
```
public static final ConfigOption<Boolean> DB_CACHE
```
  - DB_CACHE_SIZE
```
public static final ConfigOption<Double> DB_CACHE_SIZE
```
    The size of the database level cache. If this value is between 0.0 (strictly bigger) and 1.0 (strictly smaller), then it is interpreted as a percentage of the total heap space available to the JVM this JanusGraph instance is running in. If this value is bigger than 1.0 it is interpreted as an absolute size in bytes.
  - DB_CACHE_CLEAN_WAIT
```
public static final ConfigOption<Integer> DB_CACHE_CLEAN_WAIT
```
    How long the database level cache will keep keys expired while the mutations that triggered the expiration are being persisted. This value should be larger than the time it takes for persisted mutations to become visible. This setting only ever makes sense for distributed storage backends where writes may be accepted but are not immediately readable.
  - DB_CACHE_TIME
```
public static final ConfigOption<Long> DB_CACHE_TIME
```
    The default expiration time for elements held in the database level cache. This is the time period before JanusGraph will check against storage backend for a newer query answer. Setting this value to 0 will cache elements forever (unless they get evicted due to space constraints). This only makes sense when this is the only JanusGraph instance interacting with a storage backend.
  - TX_CACHE_SIZE
```
public static final ConfigOption<Integer> TX_CACHE_SIZE
```
    Configures the maximum number of recently-used vertices cached by a transaction. The smaller the cache size, the less memory a transaction can consume at maximum. For many concurrent, long running transactions in memory constraint environments, reducing the cache size can avoid OutOfMemory and GC limit exceeded exceptions. Note, however, that all modifications in a transaction must always be kept in memory and hence this setting does not have much impact on write intense transactions. Those must be split into smaller transactions in the case of memory errors.
    The recently-used vertex cache can contain both dirty and clean vertices, that is, both vertices which have been created or updated in the current transaction and vertices which have only been read in the current transaction.
  - TX_DIRTY_SIZE
```
public static final ConfigOption<Integer> TX_DIRTY_SIZE
```
    Configures the initial size of the dirty (modified) vertex map used by a transaction. All vertices created or updated by a transaction are held in that transaction's dirty vertex map until the transaction commits. This option sets the initial size of the dirty map. Unlike TX_CACHE_SIZE, this is not a maximum. The transaction will transparently allocate more space to store dirty vertices if this initial size hint is exceeded. Transactions that know how many vertices they are likely to modify a priori can avoid resize costs associated with growing the dirty vertex data structure by setting this option.
  - STORAGE_NS
```
public static final ConfigNamespace STORAGE_NS

```
public static final ConfigOption<Boolean> STORAGE_READONLY

  - STORAGE_BATCH
```
public static final ConfigOption<Boolean> STORAGE_BATCH
```

  - STORAGE_TRANSACTIONAL
```
public static final ConfigOption<Boolean> STORAGE_TRANSACTIONAL
```
    Enables transactions on storage backends that support them
  - ASSIGN_TIMESTAMP
```
public static final ConfigOption<Boolean> ASSIGN_TIMESTAMP
```
  - BUFFER_SIZE
```
public static final ConfigOption<Integer> BUFFER_SIZE
```
    Buffers graph mutations locally up to the specified number before persisting them against the storage backend. Set to 0 to disable buffering. Buffering is disabled automatically if the storage backend does not support buffered mutations.
  - STORAGE_WRITE_WAITTIME
```
public static final ConfigOption<Duration> STORAGE_WRITE_WAITTIME
```
  - STORAGE_READ_WAITTIME
```
public static final ConfigOption<Duration> STORAGE_READ_WAITTIME
```
  - PARALLEL_BACKEND_OPS
```
public static final ConfigOption<Boolean> PARALLEL_BACKEND_OPS
```
    If enabled, JanusGraph attempts to parallelize storage operations against the storage backend using a fixed thread pool shared across the entire JanusGraph graph database instance. Parallelization is only applicable to certain storage operations and can be beneficial when the operation is I/O bound.
  - PARALLEL_BACKEND_EXECUTOR_SERVICE

  - LOCK_CLEAN_EXPIRED
```
public static final ConfigOption<Boolean> LOCK_CLEAN_EXPIRED
```
    Whether to attempt to delete expired locks from the storage backend. True will attempt to delete expired locks in a background daemon thread. False will never attempt to delete expired locks. This option is only meaningful for the default lock backend.
    
    See Also:

  - IDS_NS
```
public static final ConfigNamespace IDS_NS
```
  - IDS_BLOCK_SIZE
```
public static final ConfigOption<Integer> IDS_BLOCK_SIZE
```
    Size of the block to be acquired. Larger block sizes require fewer block applications but also leave a larger fraction of the id pool occupied and potentially lost. For write heavy applications, larger block sizes should be chosen.
  - IDS_STORE_NAME
```
public static final ConfigOption<String> IDS_STORE_NAME
```
    The name of the ID store. Currently this defaults to janusgraph_ids. You can override the ID store to facilitate migration from JanusGraph's predecessor, Titan. Previously, this KCVStore was named titan_ids.
  - IDS_FLUSH
```
public static final ConfigOption<Boolean> IDS_FLUSH
```
    If flush ids is enabled, vertices and edges are assigned ids immediately upon creation. If not, then ids are only assigned when the transaction is committed.
  - IDS_RENEW_TIMEOUT
```
public static final ConfigOption<Duration> IDS_RENEW_TIMEOUT
```
    The number of milliseconds that the JanusGraph id pool manager will wait before giving up on allocating a new block of ids. Note, that failure to allocate a new id block will cause the entire database to fail, hence this value should be set conservatively. Choose a high value if there is a lot of contention around id allocation.
  - IDS_RENEW_BUFFER_PERCENTAGE
```
public static final ConfigOption<Double> IDS_RENEW_BUFFER_PERCENTAGE
```
    Configures when the id pool manager will attempt to allocate a new id block. When all but the configured percentage of the current block is consumed, a new block will be allocated. Larger values should be used if a lot of ids are allocated in a short amount of time. Value must be in (0,1].
  - IDAUTHORITY_NS
```
public static final ConfigNamespace IDAUTHORITY_NS
```
  - IDAUTHORITY_WAIT
```
public static final ConfigOption<Duration> IDAUTHORITY_WAIT
```
    The number of milliseconds the system waits for an id block application to be acknowledged by the storage backend. Also, the time waited after the application before verifying that the application was successful.
  - IDAUTHORITY_CONFLICT_AVOIDANCE
```
public static final ConfigOption<ConflictAvoidanceMode> IDAUTHORITY_CONFLICT_AVOIDANCE
```
    Sets the strategy used by ConsistentKeyIDAuthority to avoid contention in ID block allocation between JanusGraph instances concurrently sharing a single distributed storage backend.
  - IDAUTHORITY_CAV_RETRIES
```
public static final ConfigOption<Integer> IDAUTHORITY_CAV_RETRIES
```
    When JanusGraph allocates IDs with ConflictAvoidanceMode.GLOBAL_AUTO configured, it picks a random unique ID marker and attempts to allocate IDs from a partition using the marker. The ID markers function as subpartitions with each ID partition. If the attempt fails because that partition + unique id combination is already completely allocated, then JanusGraph will generate a new random unique ID and try again. This controls the maximum number of attempts before JanusGraph assumes the entire partition is allocated and fails the request. It must be set to at least 1 and should generally be set to 3 or more.
    This setting has no effect when IDAUTHORITY_CONFLICT_AVOIDANCE is not configured to ConflictAvoidanceMode.GLOBAL_AUTO.
  - IDAUTHORITY_CAV_BITS
```
public static final ConfigOption<Integer> IDAUTHORITY_CAV_BITS
```
    Configures the number of bits of JanusGraph assigned ids that are reserved for a unique id marker that allows the id allocation to be scaled over multiple sub-clusters and to reduce race-conditions when a lot of JanusGraph instances attempt to allocate ids at the same time (e.g. during parallel bulk loading) IMPORTANT: This should never ever, ever be modified from its initial value and ALL JanusGraph instances must use the same value. Otherwise, data corruption will occur. This setting has no effect when IDAUTHORITY_CONFLICT_AVOIDANCE is configured to ConflictAvoidanceMode.NONE. However, note that while the conflict avoidance mode can be changed, this setting cannot ever be changed and must therefore be considered a priori.
  - IDAUTHORITY_CAV_TAG
```
public static final ConfigOption<Integer> IDAUTHORITY_CAV_TAG
```
    Unique id marker to be used by this JanusGraph instance when allocating ids. The unique id marker must be non-negative and fit within the number of unique id bits configured. By assigning different unique id markers to individual JanusGraph instances it can be assured that those instances don't conflict with one another when attempting to allocate new id blocks. IMPORTANT: The configured unique id marker must fit within the configured unique id bit width. This setting has no effect when IDAUTHORITY_CONFLICT_AVOIDANCE is configured to ConflictAvoidanceMode.NONE.

```
    Whether to enable basic timing and operation count monitoring on backend methods using the com.codahale.metrics package.
  - METRICS_PREFIX_DEFAULT
```
public static final String METRICS_PREFIX_DEFAULT
```
    This is the prefix used outside of a graph database configuration, or for operations where a system-internal transaction is necessary as an implementation detail. It currently can't be modified, though there is no substantial technical obstacle preventing it from being configured -- some kind of configuration object is in scope everywhere it is used, and it could theoretically be stored in and read from that object.

    Default = #METRICS_PREFIX_DEFAULT
  - METRICS_MERGE_STORES
```
public static final ConfigOption<Boolean> METRICS_MERGE_STORES
```
    Whether to aggregate measurements for the edge store, vertex index, edge index, and ID store.
    If true, then metrics for each of these backends will use the same metric name ("stores"). All of their measurements will be combined. This setting measures the sum of JanusGraph's backend activity without distinguishing between contributions of its various internal stores.
    If false, then metrics for each of these backends will use a unique metric name ("idStore", "edgeStore", "vertexIndex", and "edgeIndex"). This setting exposes the activity associated with each backend component, but it also multiplies the number of measurements involved by four.
    This option has no effect when BASIC_METRICS is false.

```
public static final ConfigOption<String> METRICS_JMX_AGENTID
```
    The JMX agentId through which to report Metrics. Calling MBeanServerFactory.findMBeanServer(String) on this value must return exactly one MBeanServer at runtime. If null, then Metrics applies its default value.
