Types

object Companion

CompressionType

enum CompressionType : Enum<LevelDBOptions.CompressionType>

Enum representing the types of compression algorithms that can be used for compressing data blocks in LevelDB.

Properties

blockRestartInterval

val blockRestartInterval: Int = 16

Number of keys between restart points for delta encoding of keys.

val blockSize: Int

Approximate size of user data packed per block, in bytes. Default is 4 KB.

val compression: LevelDBOptions.CompressionType

Compression algorithm to use for blocks.

createIfMissing

val createIfMissing: Boolean = true

Whether to create the database if it does not exist.

val errorIfExists: Boolean = false

Whether to throw an error if the database already exists.

maxBytesForLevelBase

val maxBytesForLevelBase: Long

Maximum bytes for level base. Default is 10 MB.

maxBytesForLevelMultiplier

val maxBytesForLevelMultiplier: Int = 10

Multiplier for the maximum bytes for levels.

val maxFileSize: Long

Maximum size of a single file, in bytes. Default is 2 MB.

val maxOpenFiles: Int = 1000

Maximum number of open files that can be used by the database.

val paranoidChecks: Boolean = false

Whether to perform paranoid checks for file consistency.

writeBufferSize

val writeBufferSize: Long

Amount of data to build up in memory (backed by an unsorted log on disk) before converting to a sorted on-disk file, in bytes. Default is 4 MB.
