[Pytables-users] Switch off implicit flushing?

[Norbert N. <No...@ne...>]

Hi there,

I understand, that pytables buffers data until flush() is called. I also 
understand, that this buffer may also be flushed automatically when it is 
full.

Would it be possible to prohibit this automatic flushing?

The idea behind this is, that I would like to have the h5-file intact at least 
with a good probability if the program is interrupted or breaks down. If it 
would be possible to defer all writing actions to an explicit call of flush() 
(or the closing of the file), I could simply write to pytables in some random 
order, and then just call flush() when the data is in a coherent state. Even 
though this will not give us real atomic operations, it would still be good 
enough for many applications that continuously write to a file.

For performance reasons, this should probably be an option.

It should also be clear which operations are buffered at all.

Greetings,
Norbert
