      • withChunkLengthInKb

        public TableOptions.CompressionOptions withChunkLengthInKb​(Integer chunkLengthInKb)
        Description copied from class: TableOptions.CompressionOptions
        On disk, SSTables are compressed by block to allow random reads. This subproperty of compression defines the size (in KB) of the block. Values larger than the default value might improve the compression rate, but increases the minimum size of data to be read from disk when a read occurs. The default value is a good middle-ground for compressing tables. Adjust compression size to account for read/write access patterns (how much data is typically requested at once) and the average size of rows in the table.

        If no call is made to this method, the default value set by Cassandra is 54.

        Overrides:
        withChunkLengthInKb in class TableOptions.CompressionOptions
        Parameters:
        chunkLengthInKb - the new value.
        Returns:
        this object (for call chaining).

      • withCRCCheckChance

        public TableOptions.CompressionOptions withCRCCheckChance​(Double crcCheckChance)
        Description copied from class: TableOptions.CompressionOptions
        When compression is enabled, each compressed block includes a checksum of that block for the purpose of detecting disk bitrate and avoiding the propagation of corruption to other replica. This option defines the probability with which those checksums are checked during read. By default they are always checked. Set to 0 to disable checksum checking and to 0.5, for instance, to check them on every other read.

        If no call is made to this method, the default value set by Cassandra is 1.0 (always check).

        Overrides:
        withCRCCheckChance in class TableOptions.CompressionOptions
        Parameters:
        crcCheckChance - the new value.
        Returns:
        this object (for call chaining).
