kmr4py

Module kmr4py

Python Binding for KMR Map-Reduce Library. This provides straightforward wrappers to the C routines. See more abort KMR at "http://mt.aics.riken.jp/kmr". All key-value data is stored in C structures after encoding/decoding Python objects to byte arrays in C. Documentation in Python is minimum, so please refer to the documentation in C.

Variables
	kmrso = `ctypes.CDLL("libkmr.so")` kmrso holds a libkmr.so library object.
	cpickle_protocol = `0` cpickle_protocol specifies a protocol used in encoding/decoding key-value fields.
	warning_function = `warnings.warn` warning_function specifies the function used to issue warnings.
	ignore_exceptions_in_map_fn = `True` ignore_exceptions_in_map_fn=True makes exceptions ignored.
	print_backtrace_in_map_fn = `True` print_backtrace_in_map_fn=True makes backtraces are printed at exceptions in mapper/reducer functions.
	force_null_terminate_in_cstring = `True` force_null_terminate_in_cstring specifies to add a null-terminator in C strings.

Variables Details

cpickle_protocol

cpickle_protocol specifies a protocol used in encoding/decoding key-value fields. NOTE: The highest protocol of cpickle (value 2) is avoided because it fails to encode/decode integer zero in python-2.7.10, gcc-4.8.2, x86-64.

Value:

force_null_terminate_in_cstring

force_null_terminate_in_cstring specifies to add a null-terminator in C strings. Do not change it while some KVS'es are live.

Value:

True
