[−][src]Struct exonum_merkledb::DbOptions
Options for the database.
These parameters apply to the underlying database of Exonum, currently RocksDB
.
Fields (Non-exhaustive)
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.max_open_files: Option<i32>
Number of open files that can be used by the database.
The underlying database opens multiple files during operation. If your system has a limit on the number of files which can be open simultaneously, you can adjust this option to match the limit. Note, that limiting the number of simultaneously open files might slow down the speed of database operation.
Defaults to None
, meaning that the number of open files is unlimited.
create_if_missing: bool
An option to indicate whether the system should create a database or not, if it's missing.
This option applies to the cases when a node was switched off and is on again. If the database cannot be found at the indicated path and this option is switched on, a new database will be created at that path and blocks will be included therein.
Defaults to true
.
compression_type: CompressionType
An algorithm used for database compression.
Defaults to CompressionType::None
, meaning there is no compression.
