otp_plan
when using toID
with thanks to @temporalistaVersion 0.5.0 is a significant rewrite of the package focusing on substantially faster routing. The package has moved from using multiple R workers requesting and parsing results from OTP to a two stage process. Stage 1 uses curl
to send asynchronous requests to OTP. This stage should be as fast as OTP, and supports OTP's limit of 1.25x the number of cores. Stage 2 parses the JSON and converts it into a form usable in R. The parsing currently uses a single thread, but has been optimised and can now parse around 700-800 routes/second which is faster than OTP at around 40-50 routes/second/core.
Overall the new process is 3-4 times faster than v0.4.0 and uses less memory. Future development may add mulitcore support to the parsing stage for further speed improvements.

Note that this version makes minor changes to how results are returned, for example column order. These changes are due to the new json parser and should not affect the overall results but may affect any dependent code.
