The types supported by the file format are intended to be as minimal as possible, with a focus on how the types effect on disk storage. For example, 16-bit ints are not explicitly supported in the storage format since they are covered by 32-bit ints with an efficient encoding. This reduces the complexity of implementing readers and writers for the format. The types are:
BOOLEAN: 1 bit boolean INT32: 32 bit signed ints INT64: 64 bit signed ints INT96: 96 bit signed ints FLOAT: IEEE 32-bit floating point values DOUBLE: IEEE 64-bit floating point values BYTE_ARRAY: arbitrarily long byte arrays.
