Hi John, I'm currently working on FastBit support for compressed files. To simplify things a bit for a start, I have disabled the MMAP support and forced FastBit to use open, read, write and seek functions. Then I hooked into these functions and provided a compression layer. The problem is that just disabling the MMAP causes FastBit to use so much memory that OOM killer terminates the process for some aggregation queries.
Is there anything I can do to tell FastBit to limit the amount of memory it can use? I thought that only half of the available memory will be used by default. I've tested this issue on latest SVN revision. Thank you in advance for any help, Petr Velan
