◆ open()

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

Open a connection to a database.

error_check(wiredtiger_open(
home, NULL, "create,cache_size=5GB,log=(enabled,recover=on),statistics=(all)", &conn));
Parameters
homeThe path to the database home directory. See Database Home Directory for more information.
event_handlerAn event handler. If NULL, a default event handler is installed that writes error messages to stderr. See Message handling using the WT_EVENT_HANDLER for more information.
configconfiguration string, see Configuration Strings. Permitted values:
NameEffectValues
async = (asynchronous operations configuration options.a set of related configuration options defined below.
    enabledenable asynchronous operation.a boolean flag; default false.
    ops_maxmaximum number of expected simultaneous asynchronous operations.an integer between 1 and 4096; default 1024.
    threadsthe 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_alignmentin-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_configA 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_cursorsenable caching of cursors for reuse. This is the default value for any sessions created, and can be overridden in configuring cache_cursors in WT_CONNECTION.open_session.a boolean flag; default true.
cache_max_wait_msthe maximum number of milliseconds an application thread will wait for space to be available in cache before giving up. Default will wait forever.an integer greater than or equal to 0; default 0.
cache_overflow = (cache overflow configuration options.a set of related configuration options defined below.
    file_maxThe maximum number of bytes that WiredTiger is allowed to use for its cache overflow mechanism. If the cache overflow file exceeds this size, a panic will be triggered. The default value means that the cache overflow file is unbounded and may use as much space as the filesystem will accommodate. The minimum non-zero setting is 100MB.an integer greater than or equal to 0; default 0.
)
cache_overheadassume 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_sizemaximum 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_sizewait 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.
    waitseconds to wait between each checkpoint; setting this value above 0 configures periodic checkpoints.an integer between 0 and 100000; default 0.
)
checkpoint_syncflush files to stable storage when closing or writing checkpoints.a boolean flag; default true.
compatibility = (set compatibility version of database. Changing the compatibility version requires that there are no active operations for the duration of the call.a set of related configuration options defined below.
    releasecompatibility release version string.a string; default empty.
     require_maxrequired maximum compatibility version of existing data files. Must be greater than or equal to any release version set in the release setting. Has no effect if creating the database.a string; default empty.
    require_minrequired minimum compatibility version of existing data files. Must be less than or equal to any release version set in the release setting. Has no effect if creating the database.a string; default empty.
)
config_basewrite 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. See WiredTiger.basecfg file for more information.a boolean flag; default true.
createcreate the database if it does not exist.a boolean flag; default false.
debug_mode = (control the settings of various extended debugging features.a set of related configuration options defined below.
     checkpoint_retentionadjust log archiving to retain the log records of this number of checkpoints. Zero or one means perform normal archiving.an integer between 0 and 1024; default 0.
    evictionif true, modify internal algorithms to change skew to force lookaside eviction to happen more aggressively. This includes but is not limited to not skewing newest, not favoring leaf pages, and modifying the eviction score mechanism.a boolean flag; default false.
    rollback_errorreturn a WT_ROLLBACK error from a transaction operation about every Nth operation to simulate a collision.an integer between 0 and 10M; default 0.
     table_loggingif true, write transaction related information to the log for all operations, even operations for tables with logging turned off. This setting introduces a log format change that may break older versions of WiredTiger. These operations are informational and skipped in recovery.a boolean flag; default false.
)
direct_ioUse O_DIRECT on POSIX systems, and FILE_FLAG_NO_BUFFERING on Windows to access files. 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. If a system wide encryptor is set, it is also used for encrypting data files and tables, unless encryption configuration is explicitly set for them when they are created with WT_SESSION::create.a set of related configuration options defined below.
    keyidAn identifier that identifies a unique instance of the encryptor. It is stored in clear text, and thus is available when the wiredtiger database is reopened. On the first use of a (name, keyid) combination, the WT_ENCRYPTOR::customize function is called with the keyid as an argument.a string; default empty.
    namePermitted values are "none" or custom encryption engine name created with WT_CONNECTION::add_encryptor. See Encryptors for more information.a string; default none.
    secretkeyA string that is passed to the WT_ENCRYPTOR::customize function. It is never stored in clear text, so must be given to any subsequent wiredtiger_open calls to reopen the database. It must also be provided to any "wt" commands used with this database.a string; default empty.
)
error_prefixprefix string for error messages.a string; default empty.
eviction = (eviction configuration options.a set of related configuration options defined below.
    threads_maxmaximum number of threads WiredTiger will start to help evict pages from cache. The number of threads started will vary depending on the current eviction load. Each eviction worker thread uses a session from the configured session_max.an integer between 1 and 20; default 8.
     threads_minminimum number of threads WiredTiger will start to help evict pages from cache. The number of threads currently running will vary depending on the current eviction load.an integer between 1 and 20; default 1.
)
eviction_checkpoint_targetperform eviction at the beginning of checkpoints to bring the dirty content in cache to this level. It is a percentage of the cache size if the value is within the range of 0 to 100 or an absolute size when greater than 100. The value is not allowed to exceed the cache_size. Ignored if set to zero or in_memory is true.an integer between 0 and 10TB; default 1.
eviction_dirty_targetperform eviction in worker threads when the cache contains at least this much dirty content.

The value is not allowed to exceed the cache_size.an integer between 1 and 10TB; default 5.
eviction_dirty_triggertrigger application threads to perform eviction when the cache contains at least this much dirty content. It is a percentage of the cache size if the value is within the range of 1 to 100 or an absolute size when greater than 100. The value is not allowed to exceed the cache_size. This setting only alters behavior if it is lower than eviction_trigger.an integer between 1 and 10TB; default 20.
eviction_targetperform eviction in worker threads when the cache contains at least this much content. It is a percentage of the cache size if the value is within the range of 10 to 100 or an absolute size when greater than 100. The value is not allowed to exceed the cache_size.an integer between 10 and 10TB; default 80.
eviction_triggertrigger application threads to perform eviction when the cache contains at least this much content.

exclusivefail if the database already exists, generally used with the create option.a boolean flag; default false.
extensionslist 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_extendfile 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). If set to 0, disable the file extension for the set type. For log files, the allowed range is between 100KB and 2GB; values larger than the configured maximum log size and the default config would extend log files in allocations of the maximum log file size.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_minimumnumber 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_timeamount 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_intervalinterval in seconds at which to check for files that are inactive and close them.an integer between 1 and 100000; default 10.

    paththe name of a directory into which operation tracking 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 ".".
)
readonlyopen connection in read-only mode. The database must exist. All methods that may modify a database are disabled. See Database read-only mode for more information.a boolean flag; default false.
salvageopen connection and salvage any WiredTiger-owned database and log files that it detects as corrupted. This API should only be used after getting an error return of WT_TRY_SALVAGE. Salvage rebuilds files in place, overwriting existing files. We recommend making a backup copy of all files with the WiredTiger prefix prior to passing this flag.a boolean flag; default false.
session_maxmaximum expected number of sessions (including server threads).an integer greater than or equal to 1; default 100.
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 shared cache can not have absolute values configured for cache eviction settings.a set of related configuration options defined below.
    chunkthe granularity that a shared cache is redistributed.an integer between 1MB and 10TB; default 10MB.
    namethe name of a cache that is shared between databases or "none" when no shared cache is configured.a string; default none.
    quotamaximum size of cache this database can be allocated from the shared cache. Defaults to the entire shared cache size.an integer; default 0.
    reserveamount of cache this database is guaranteed to have available from the shared cache. This setting is per database. Defaults to the chunk size.an integer; default 0.
    sizemaximum 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.
)
statisticsMaintain 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.
    jsonencode statistics in JSON format.a boolean flag; default false.
    on_closelog statistics on database close.a boolean flag; default false.
    paththe 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 ".".
    sourcesif 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.
    timestampa 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".
    waitseconds 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.
    enabledwhether 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.
    methodthe 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_environmentuse 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_privuse 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.
verboseenable messages for various events. Options are given as a list, such as "verbose=[evictserver,read]".a list, with values chosen from the following options: "api", "block", "checkpoint", "checkpoint_progress", "compact", "compact_progress", "error_returns", "evict", "evict_stuck", "evictserver", "fileops", "handleops", "log", "lookaside", "lookaside_activity", "lsm", "lsm_manager", "metadata", "mutex", "overflow", "read", "rebalance", "reconcile", "recovery", "recovery_progress", "salvage", "shared_cache", "split", "temporary", "thread_group", "timestamp", "transaction", "verify", "version", "write"; default empty.
write_throughUse 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.
