In Texis version 8 and later, the
blobz SQL type was added.
This type is similar to the
blob type, in that it is intended
for large, infrequently-accessed fields and is stored in a separate
.blb file. However,
blobz fields may be compressed on
disk to save space, and are automatically uncompressed when read and
converted to another type.
Caveat: A table created with (a) blobz column(s) should not be accessed nor modified by Texis version 7 or earlier, or errors and/or corruption may result. Some versions prior to 8 may be able to handle blobz data; however support and/or correct behavior is not ensured.
