Member Function Documentation

open()

static Connection com.wiredtiger.db.wiredtiger.open ( String  home, String  config  ) throws com.wiredtiger.db.WiredTigerException

static

Open a connection to a database.

        ret = wiredtiger_open(home, NULL,
            "create,cache_size=5GB,log=(enabled,recover=on)", &conn);

Parameters

	home	The path to the database home directory. See Database Home Directory for more information.
	errhandler	An error handler. If NULL, a builtin error handler is installed that writes error messages to stderr. See Error handling using the WT_EVENT_HANDLER for more information.
	config	Configuration string, see Configuration Strings. Permitted values: Name Effect Values async = ( asynchronous operations configuration options. a set of related configuration options defined below.     enabled enable asynchronous operation. a boolean flag; default false.     ops_max maximum number of expected simultaneous asynchronous operations. an integer between 1 and 4096; default 1024.     threads the number of worker threads to service asynchronous requests. Each worker thread uses a session from the configured session_max. an integer between 1 and 20; default 2. ) buffer_alignment in-memory alignment (in bytes) for buffers used for I/O. The default value of -1 indicates a platform-specific alignment value should be used (4KB on Linux systems when direct I/O is configured, zero elsewhere). an integer between -1 and 1MB; default -1. builtin_extension_config A structure where the keys are the names of builtin extensions and the values are passed to WT_CONNECTION::load_extension as the config parameter (for example, builtin_extension_config={zlib={compression_level=3}}). a string; default empty. cache_overhead assume the heap allocator overhead is the specified percentage, and adjust the cache usage by that amount (for example, if there is 10GB of data in cache, a percentage of 10 means WiredTiger treats this as 11GB). This value is configurable because different heap allocators have different overhead and different workloads will have different heap allocation sizes and patterns, therefore applications may need to adjust this value based on allocator choice and behavior in measured workloads. an integer between 0 and 30; default 8. cache_size maximum heap memory to allocate for the cache. A database should configure either cache_size or shared_cache but not both. an integer between 1MB and 10TB; default 100MB. checkpoint = ( periodically checkpoint the database. Enabling the checkpoint server uses a session from the configured session_max. a set of related configuration options defined below.     log_size wait for this amount of log record bytes to be written to the log between each checkpoint. If non-zero, this value will use a minimum of the log file size. A database can configure both log_size and wait to set an upper bound for checkpoints; setting this value above 0 configures periodic checkpoints. an integer between 0 and 2GB; default 0.     wait seconds to wait between each checkpoint; setting this value above 0 configures periodic checkpoints. an integer between 0 and 100000; default 0. ) checkpoint_sync flush files to stable storage when closing or writing checkpoints. a boolean flag; default true. config_base write the base configuration file if creating the database. If false in the config passed directly to wiredtiger_open, will ignore any existing base configuration file in addition to not creating one.

Options are given as a list, such as "direct_io=[data]". Configuring direct_io requires care, see Direct I/O for important warnings. Including "data" will cause WiredTiger data files to use direct I/O, including "log" will cause WiredTiger log files to use direct I/O, and including "checkpoint" will cause WiredTiger data files opened at a checkpoint (i.e: read only) to use direct I/O. direct_io should be combined with write_through to get the equivalent of O_DIRECT on Windows. a list, with values chosen from the following options: "checkpoint", "data", "log"; default empty. encryption = ( configure an encryptor for system wide metadata and logs.

Must be less than eviction_trigger. an integer between 10 and 99; default 80. eviction_trigger trigger application threads to perform eviction when the cache contains at least this much content, expressed as a percentage of the total cache size. an integer between 10 and 99; default 95. exclusive fail if the database already exists, generally used with the create option. a boolean flag; default false. extensions list of shared library extensions to load (using dlopen). Any values specified to a library extension are passed to WT_CONNECTION::load_extension as the config parameter (for example, extensions=(/path/ext.so={entry=my_entry})). a list of strings; default empty. file_extend file extension configuration. If set, extend files of the set type in allocations of the set size, instead of a block at a time as each new block is written. For example, file_extend=(data=16MB). a list, with values chosen from the following options: "data", "log"; default empty. file_manager = ( control how file handles are managed. a set of related configuration options defined below.     close_handle_minimum number of handles open before the file manager will look for handles to close. an integer greater than or equal to 0; default 250.     close_idle_time amount of time in seconds a file handle needs to be idle before attempting to close it. A setting of 0 means that idle handles are not closed. an integer between 0 and 100000; default 30.     close_scan_interval interval in seconds at which to check for files that are inactive and close them. an integer between 1 and 100000; default 10. ) in_memory keep data in-memory only. See In-memory databases for more information. a boolean flag; default false. log = ( enable logging. Enabling logging uses three sessions from the configured session_max. a set of related configuration options defined below.     archive automatically archive unneeded log files. a boolean flag; default true.     compressor configure a compressor for log records. Permitted values are "none" or custom compression engine name created with WT_CONNECTION::add_compressor.

If the value is not an absolute path, the path is relative to the database home (see Absolute paths for more information). a string; default ".".     prealloc pre-allocate log files. a boolean flag; default true.     recover run recovery or error if recovery needs to run after an unclean shutdown. a string, chosen from the following options: "error", "on"; default on.     zero_fill manually write zeroes into log files. a boolean flag; default false. ) lsm_manager = ( configure database wide options for LSM tree management. The LSM manager is started automatically the first time an LSM tree is opened. The LSM manager uses a session from the configured session_max. a set of related configuration options defined below.     merge merge LSM chunks where possible. a boolean flag; default true.     worker_thread_max Configure a set of threads to manage merging LSM trees in the database. Each worker thread uses a session handle from the configured session_max. an integer between 3 and 20; default 4. ) mmap Use memory mapping to access files when possible. a boolean flag; default true. multiprocess permit sharing between processes (will automatically start an RPC server for primary processes and use RPC for secondary processes).

See Database read-only mode for more information. a boolean flag; default false. session_max maximum expected number of sessions (including server threads). an integer greater than or equal to 1; default 100. session_table_cache Maintain a per-session cache of tables. a boolean flag; default true. shared_cache = ( shared cache configuration options. A database should configure either a cache_size or a shared_cache not both. Enabling a shared cache uses a session from the configured session_max. a set of related configuration options defined below.     chunk the granularity that a shared cache is redistributed. an integer between 1MB and 10TB; default 10MB.     name the name of a cache that is shared between databases or "none" when no shared cache is configured. a string; default none.     quota maximum size of cache this database can be allocated from the shared cache.

Defaults to the chunk size. an integer; default 0.     size maximum memory to allocate for the shared cache. Setting this will update the value if one is already set. an integer between 1MB and 10TB; default 500MB. ) statistics Maintain database statistics, which may impact performance. Choosing "all" maintains all statistics regardless of cost, "fast" maintains a subset of statistics that are relatively inexpensive, "none" turns off all statistics. The "clear" configuration resets statistics after they are gathered, where appropriate (for example, a cache size statistic is not cleared, while the count of cursor insert operations will be cleared). When "clear" is configured for the database, gathered statistics are reset each time a statistics cursor is used to gather statistics, as well as each time statistics are logged using the statistics_log configuration. See Statistics for more information. a list, with values chosen from the following options: "all", "cache_walk", "fast", "none", "clear", "tree_walk"; default none. statistics_log = ( log any statistics the database is configured to maintain, to a file. See Statistics for more information. Enabling the statistics log server uses a session from the configured session_max. a set of related configuration options defined below.     json encode statistics in JSON format. a boolean flag; default false.     on_close log statistics on database close. a boolean flag; default false.     path the name of a directory into which statistics files are written. The directory must already exist. If the value is not an absolute path, the path is relative to the database home (see Absolute paths for more information). a string; default ".".     sources if non-empty, include statistics for the list of data source URIs, if they are open at the time of the statistics logging. The list may include URIs matching a single data source ("table:mytable"), or a URI matching all data sources of a particular type ("table:"). a list of strings; default empty.     timestamp a timestamp prepended to each log record, may contain strftime conversion specifications, when json is configured, defaults to "%FT%Y.000Z". a string; default "%b %d %H:%M:%S".     wait seconds to wait between each write of the log records; setting this value above 0 configures statistics logging. an integer between 0 and 100000; default 0. ) transaction_sync = ( how to sync log records when the transaction commits. a set of related configuration options defined below.     enabled whether to sync the log on every commit by default, can be overridden by the sync setting to WT_SESSION::commit_transaction. a boolean flag; default false.     method the method used to ensure log records are stable on disk, see Commit-level durability for more information. a string, chosen from the following options: "dsync", "fsync", "none"; default fsync. ) use_environment use the WIREDTIGER_CONFIG and WIREDTIGER_HOME environment variables if the process is not running with special privileges. See Database Home Directory for more information. a boolean flag; default true. use_environment_priv use the WIREDTIGER_CONFIG and WIREDTIGER_HOME environment variables even if the process is running with special privileges. See Database Home Directory for more information. a boolean flag; default false. verbose enable messages for various events. Only available if WiredTiger is configured with –enable-verbose. Options are given as a list, such as "verbose=[evictserver,read]". a list, with values chosen from the following options: "api", "block", "checkpoint", "compact", "evict", "evict_stuck", "evictserver", "fileops", "handleops", "log", "lsm", "lsm_manager", "metadata", "mutex", "overflow", "read", "rebalance", "reconcile", "recovery", "recovery_progress", "salvage", "shared_cache", "split", "temporary", "thread_group", "transaction", "verify", "version", "write"; default empty. write_through Use FILE_FLAG_WRITE_THROUGH on Windows to write to files. Ignored on non-Windows systems. Options are given as a list, such as "write_through=[data]". Configuring write_through requires care, see Direct I/O for important warnings. Including "data" will cause WiredTiger data files to write through cache, including "log" will cause WiredTiger log files to write through cache. write_through should be combined with direct_io to get the equivalent of POSIX O_DIRECT on Windows. a list, with values chosen from the following options: "data", "log"; default empty. Additionally, if files named WiredTiger.config or WiredTiger.basecfg appear in the WiredTiger home directory, they are read for configuration values (see WiredTiger.config file and WiredTiger.basecfg file for details). See Configuration ordering for ordering of the configuration mechanisms.
