**Describe the solution you'd like** The bitfunnel paper contained some additions to the `partitioned_elias_fano` codebase which allowed measuring queries per second with multiple threads. see here: `https://github.com/BitFunnel/partitioned_elias_fano/blob/master/Runner/QueryLogRunner.cpp#L56` It would be...
**Describe the bug** Ingesting plaintext records via stdin seems very slow (`12`MiB/sec) even though `60` worker threads are used. I suspect this has to do with https://en.cppreference.com/w/cpp/io/ios_base/sync_with_stdio Before I disabled...
Should be possible by 1. Performing interval_symbols on the class WT 2. For each of the classes perform interval_symbols on the offset WTs
This pull request adds functionality to the int-vector-mapper (#232) such as [x] typedef for a `read_only_mapper` [x] support class which allows the creation of output buffer: `write_out_buffer` [x] support class...
