Property Documentation
◆ options
| getset |
Optional parameters.
- MAX_SEGMENT_SIZE: Maximum size of an individual segment file.
- SEGMENT_COUNT: Approximate number of segment files to split the WAL across. Must be at least two.
- SYNC_POLICY: Maximum size of an individual segment file. Supported values:
- NONE: Disables the WAL.
- BACKGROUND: WAL entries are periodically written instead of immediately after each operation.
- FLUSH: Protects entries in the event of a database crash.
- FSYNC: Protects entries in the event of an OS crash.
- FLUSH_FREQUENCY: Specifies how frequently WAL entries are written with background sync. This is a global setting and can only be used with the system options.table_names specifier ’*’.
- CHECKSUM: If TRUE each entry will be checked against a protective checksum. Supported values:The default value is TRUE.
- OVERRIDE_NON_DEFAULT: If TRUE tables with unique WAL settings will be overridden when applying a system level change. Supported values:The default value is FALSE.
- RESTORE_SYSTEM_SETTINGS: If TRUE tables with unique WAL settings will be reverted to the current global settings. Cannot be used in conjunction with any other option. Supported values:The default value is FALSE.
- PERSIST: If TRUE and a system-level change was requested, the system configuration will be written to disk upon successful application of this request. This will commit the changes from this request and any additional in-memory modifications. Supported values:The default value is TRUE.
The default value is an empty Dictionary.
