    The type system is derived from Java types.

    Type NameStorage bitsDescription
    boolean1boolean true or false
    byte8signed integer -128 to 127
    short16signed integer -32768 to 32767
    char16unicode character
    int32signed integer 0x80000000 to 0x7fffffff
    float32single precision IEEE 754 floating point value
    symbol32Symbols are stored as 32-bit signed indexes from symbol table. Each index will have a corresponding string value. Translation from index to string value is done automatically when data is being written or read. Symbol table is stored separately from column.
    string32+n16Length-prefixed sequence of UTF-16 encoded characters whose length is stored as signed 32-bit integer with maximum value of 0x7fffffff.
    long64signed integer 0x8000000000000000L to 0x7fffffffffffffffL
    date64signed offset in milliseconds from Unix Epoch
    timestamp64signed offset in microseconds from Unix Epoch
    double64double precision IEEE 754 floating point value
    binary64+n8Length-prefixed sequence of bytes whose length is stored as signed 64-bit integer with maximum value of 0x7fffffffffffffffL.
    long256256unsigned 256-bit integer

    :::info

    BINARY field size is limited either by 64-Bit signed int (8388608 peta bytes) or disk size, whichever is smaller.

    :::

    :::info
