No append to zipped enums error

Community Support

Hello All, 

I am trying to store a compressed enumerated column using v3.3 but getting a “no append to zipped enums” error.  Is there a way around this?

Thanks

I see in the wiki

Q) Can I append to a compressed file?
A) Yes, since kdb+ v2.8 2011.11.21. Appending to compressed enum files was blocked in v3.0 2012.05.17 due to potential concurrency issues, hence these files should not be compressed.


But I am trying to store a splayed table, using .Q.dpft it compressed the sym file automatically. Is there a way to store without compressing the enums?

You have to create/set the sym file uncompressed. If you have .z.zd set it’s a bit tricky since you have to override the set:

(`:sym;17;0;2) set sym

To force kdb to set it down uncompressed.
