If the size > requested is smaller > than 16 kilobytes and cannot be satisfied by the internal buffer, the network > read will be 16 > kilobytes. If the size requested is greater than 4 megabytes, it will be > satisfied by sequential > 4 megabyte reads over the network. > This change improves the performance of FSInputStream.seek() by not closing > and re-opening the > stream, which for block blobs also involves a network operation to read the > blob metadata. Now > NativeAzureFsInputStream.seek() checks if the stream is seek-able and moves > the read position. > [^attachment-name.zip] -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
