What is the maximum string size for a field value?


The latest documentation I saw indicated the maximum string size for a field value was 64KB. Is this still the case? Is it configurable?


@Drew Thank you for moving your question over! I’m pretty sure it is still 64KB. What are you looking to store?


@Drew You can actually store strings of any size as field values. The 65k limit is for series keys. One of our engineers was able to store golang binaries in there so there really isn’t a limit. Performance might be an issue there however.


Nice! We have a use case for storing binaries. I understand performance probably won’t be optimal for this case. I think the documentation says that all the data points need to be in memory. Does this include all of the field values?


@Drew For returning queries the data will need to be pulled up into memory. But the only in memory part of the db at rest is the series index.


Great! Thanks for your help.
