Hey folks, I was contemplating having a LIKE type search on Secondary
Indexes.
LIKE_S, S_LIKE and S_LIKE_S (similiar to LIKE '%eg', 'eg% and '%eg%'
I am not sure if this has already been discussed or even an existing JIRA or
maybe something maybe I could contribute myself?
It looks like the best way to-do this would be to add some additional
properties to IndexExpression so we know we want to-do a LIKE check
pseudo coding my thoughts taking this from ColumnFamilyStore
int v =
data.metadata().getValueValidator(expression.column_name).compare(column.value(),
expression.value);
if (!satisfies(v, expression.op))
return false;
and make it something like this
if (expression.LIKE) {
if (!column.MakeItAStringValue().equalsIgnoreCase(express.value)) //this
would actually fall into a switch for S_LIKE, LIKE_S, S_LIKE_S
return false;
else {
int v =
data.metadata().getValueValidator(expression.column_name).compare(column.value(),
expression.value);
if (!satisfies(v, expression.op))
return false;
}
am i on the right track? smoking crack?
let me know please
