Unloading Data
This section explains how to unload tables and query results, using the
ybunload
client tool. The ybunload
client is a
high-performance parallel export tool that unloads data to files on the client system. The
client connects to the manager node, then distributes the work of reading and writing the data
to the compute blades. Data can be returned to the client in compressed (GZIP) or uncompressed
files. The unloaded data can be streamed out to multiple output files or combined into a
single file, depending on your requirements.
Download and install the unload client (as part of the ybtools
package) from the SMC or the Customer Support download site. Then
run the Linux and Windows executable programs:
ybunload
on Linuxybunload.exe
on Windows
