[GitHub] incubator-beam pull request #752: Beam Python GCSIO write performance improv...
GitHub user mdvorsky opened a pull request:
https://github.com/apache/incubator-beam/pull/752
Beam Python GCSIO write performance improvements.
Increased the GCS buffer size from 1MB to 8MB and introduced a 128kB buffer for the pipe.
Increasing the GCS buffer even more could improve the performance, but for the price of spending a lot of memory on buffers (which can be a problem if many GCS files are being written to concurrently).
Increasing the pipe buffer further appears to have no benefit.
