pymtbl: Python bindings for the mtbl sorted string table library
pymtbl provides a simple Pythonic wrapper for
mtbl's reader, writer, sorter, and
merger interfaces. The examples/ directory contains scripts demonstrating
each of these interfaces. The following transcript shows the basic reader and
writer interfaces:
>>> import mtbl
>>> w = mtbl.writer('example.mtbl', compression=mtbl.COMPRESSION_SNAPPY)
>>> w['key1'] = 'val1'
>>> w['key17'] = 'val17'
>>> w['key2'] = 'val2'
>>> w['key23'] = 'val23'
>>> w['key3'] = 'val3'
>>> w['key4'] = 'val4'
>>> w['key05'] = 'val05'
