Expand description

Parameters for database configuration

Database logging level. Levels higher than “notice” require a debug build.

Open environment in exclusive/monopolistic mode. Makes it possible to open a database on an NFS volume.

Maximum database size (e.g., 4TB, 8TB).

This sets the “map size” of the database. If the database grows beyond this limit, the node will stop with an “environment map size limit reached” error.

The default value is 8TB.

Database page size (e.g., 4KB, 8KB, 16KB).

Specifies the page size used by the MDBX database.

The page size determines the maximum database size. MDBX supports up to 2^31 pages, so with the default 4KB page size, the maximum database size is 8TB. To allow larger databases, increase this value to 8KB or higher.

WARNING: This setting is only configurable at database creation; changing it later requires re-syncing.

Database growth step (e.g., 4GB, 4KB)

Read transaction timeout in seconds, 0 means no timeout.

Maximum number of readers allowed to access the database concurrently.

Controls how aggressively the database synchronizes data to disk.

Returns default database arguments with configured log level and client version.

Returns the database arguments with configured log level, client version, max read transaction duration, and geometry.
