How many values with pipe separator can be added in Get query of TSDB. What will be the performance hit with long list? ANy alternative to achieve this ?

While we don't have a limit on the number of values in a long list, we have a default of a total of 4096 of those values across all filters in a single query. if the value is greater than this we don't pass that filter to HBase (to avoid a massive filter). Instead we (I think) switch to TSD side regex so HBase will return all of the data. In 2.4 we're working on a better way of using the search plugin to perform resolution.
