KVStore kvstore = KVStoreFactory.getStore(
new KVStoreConfig("kvstore", "kvlite:5000")
);
BlobStoreFileSystem fileSystem = BlobStoreFileSystem.New(
OracleNoSqlConnector.Caching(kvstore)
);
EmbeddedStorage.start(fileSystem.ensureDirectoryPath("microstream_storage"));
Configuration
When using external configuration Oracle NoSQL can be set as follows.
storage-filesystem.oracle.nosql.store-name=kvstore
storage-filesystem.oracle.nosql.helper-hosts=kvlite:5000
storage-filesystem.oracle.nosql.username=user
storage-filesystem.oracle.nosql.password=secret
Property | Description |
---|---|
store-name |
The name of the KVStore. The store name is used toguard against accidental use of the wrong host or port. The store name must consist entirely of upper or lower-case, letters and digits. |
helper-hosts |
Comma separated list containing the host and port of an active node in the KVStore. Each string has the format hostname:port. It is good practice to pass multiple hosts so that if one host is down, the system will attempt to open the next one, and so on. |
username |
Username used for authentication. |
password |
Password used for authentication. |
check-interval |
Configures the default interval for checking on data definition operation progress. |
consistency |
Configures the default read Consistency to be used when a Consistency is not specified for a particular read operation. Supported values:
|
durability |
Configures the default write Durability to be used when a Durability is not specified for a particular write operation. Supported values:
|
lob-chunk-size |
Configures the chunk size associated with the chunks used to store a LOB. |
lob-chunks-per-partition |
Configures the number of contiguous chunks that can be stored in the same partition for a given LOB. |
lob-timeout |
Configures default timeout value associated with chunk access during operations on LOBs. |
lob-verification-bytes |
Configures the number of trailing bytes of a partial LOB that must be verified against the user supplied LOB stream when resuming a putLOB operation. A value⇐0 disables verification. |
max-check-retries |
Set the number of times the client will attempt to check status for the execution of an asynchronous data definition or administrative statement execution in the face of network connection problems. |
network-roundtrip-timeout |
Configures the amount of time to allow for a single round-trip network communication with the server. This value is added to the request timeout to determine the total amount of time that the client should wait for a request to complete before timing out. |
read-zones |
Comma separated lists of zones in which nodes must be located to be used for read operations. If the argument is null, or this method has not been called, then read operations can be performed on nodes in any zone. |
registry-open-timeout |
Configures the connect/open timeout used when making RMI registry lookup requests. |
registry-read-timeout |
Configures the read timeout associated with sockets used to make RMI registry requests. Shorter timeouts result in more rapid failure detection and recovery. However, this timeout should be sufficiently long so as to allow for the longest timeout associated with a request. |
request-timeout |
Configures the default request timeout. |
sg-attrs-cache-timeout |
Sets the timeout of cached sequence generator attributes in milliseconds. |
socket-open-timeout |
Configures the open timeout used when establishing sockets used to make client requests. Shorter timeouts result in more rapid failure detection and recovery. The default open timeout (3000 milliseconds) should be adequate for most applications. |
socket-read-timeout |
Configures the read timeout associated with the underlying sockets used to make client requests. Shorter timeouts result in more rapid failure detection and recovery. However, this timeout should be sufficiently long so as to allow for the longest timeout associated with a request. |
use-async |
Specifies whether calls to the store should use the async network protocol. |
security-properties |
Configures security properties for the client. The supported properties include both authentication properties and transport properties. See oracle.kv.KVSecurityConstants for details. |
