In MySQL Cluster (ndb engine) disk based table, if a column is varchar(255)
with UNIQUE INDEX defined then,
- For Latin(default) char set, does varchar column takes fixed
- For UTF-8 (3 char wide), Does column takes Fixed
length[255*3+length] or variable chars taken care i.e., [Actual length of
data*3 + length]
I would really appreciate if someone can help me understand the behavior.
