C++ Casablanca CouchDB Sample

Producer/consumer bulk upload to CouchDB using Microsoft Casablanca REST library and Boost

Build and run

Pre-requisites

• a C++11 compiler
• boost
• Casablanca
• a copy of CouchDB running somewhere

Building

This will depend on platform, but on the Mac it looks something like

clang++ casablanca_couchdb_sample.cpp -std=c++11 -I$CASABLANCA_DIR/Release/include/ -lcpprest -L$CASABLANCA_DIR/build.release/Binaries/ -lboost_thread-mt -lboost_system -lboost_chrono -lboost_program_options

The sample shows:

• Creating JSON documents using Casablanca
• Making REST API calls using Casablanca
• Using boost threading primitives to create and upload batches of documents using a producer/consumer pattern and a shared queue

Sample showing an upload of 100000 documents with a batch size of 1000:

14:30:45 in cplusplus$ curl -XDELETE "http://127.0.0.1:5984/testdb" && curl -XPUT "http://127.0.0.1:5984/testdb" && ./a.out --d 100000 --bs 1000
{"ok":true}
{"ok":true}
produced 100000 objects.
consumed 100000 objects.
batch size was 1000 objects.
took 10.9801 seconds

rate 9107.36 docs / second

Issues

• If the number of documents is not exactly divisible by the batch size, the remainder do not get uploaded (!)
• Database URL is hard-coded
• Database is not deleted/created as part of the test run
