GEN-74: Rework the transposition process #40

Closed ymarcon closed 6 years ago

ymarcon commented 16 years ago

Jira issue originally created by user nemond:

Performance is suffering when transposing the same data multiple times.

Comment created by @plaflamme:

By profiling the process, it was noticed that the transposition process was much slower when the destination calls field already existed and needed to be loaded from disk prior to being written to.

The new GenotypingStoreTransposer class now allows deleting the destination store prior to transposing the data, effectively removing all the destination fields before writing.
