Exploring distributed BookKeeper to use in work flow for storing some state information

["Inder.dev Java" <ja...@gmail.com>]

HI,

We have workflow kind system, here I came to know that BookKeeper is highly
available storage system. I am exploring I can use BookKeeper for storing
some of the state information. I have the data in XML format. will it
support? or I should have flat line based files?

Also wanted to check How many people are working in BookKeeper? growing?
Is it a Healthy project?

greatly appreciate your help....

Cheers,
Inder Paul

Thanks for your interest, Inder Paul. BookKeeper focuses on sequential workloads and targets tasks like write-ahead logging. It supports multiple concurrent logs being written to and offers strong durability guarantees for data appended to logs. BookKeeper is not a general-purpose data store, though.

Hey Inder,

That's great news, you are exploring BookKeeper :-)



 You have mentioned XML format files, I am not sure you will get the advantage in this format with BK in any case.

Here BK support entry level write.

It is like, you can write line by line append. It mainly fits for write ahead logging. I am not sure what is your use case exactly.

Any application that requires an append storage can replace their implementations with BookKeeper.

take a look at http://zookeeper.apache.org/doc/trunk/bookkeeperOverview.html







And for the other question:

currently ~10 contributors are there for BookKeeper (from Ivan previous mail). New members are joining as well.

We are using BookKeeper in NameNode HA.  I feel it is healthy, doing many activities. It will grow infuture as well.

See the Ivan's mail recently for board report :http://www.mail-archive.com/bookkeeper-dev@zookeeper.apache.org/msg02451.html.

Start contributing to BK http://zookeeper.apache.org/bookkeeper/ , if you have interest :-)







Regards,

Uma
