Constants ¶
const ( // MessageTTLSeconds is how long an individual fully-built dto.Message lives in cache. // Short enough that reactions, embeds, and edits stay reasonably fresh on a miss. MessageTTLSeconds int64 = 300 // 5 minutes // IndexTTLSeconds is the safety-net TTL reset on the sorted-set index key on every write. // Inactive channels clean up automatically after this window. IndexTTLSeconds int64 = 86400 // 24 hours // WindowSize is the number of latest messages we keep in the window. // Must match MaxBatchSize in the message handler. WindowSize = 50 )

Functions ¶
func IDToMember ¶
IDToMember converts a message ID to the sorted-set member string.
func IndexKey ¶
IndexKey returns the Redis sorted-set key that tracks message IDs for a channel. Score = float64(message_id). Member = IDToMember(message_id).
Note on float64 precision: snowflake IDs are ~61-bit integers. float64 has 53-bit mantissa, so IDs within the same ~512-ID batch share the same float64 score. Redis then breaks ties lexicographically by member. Since all IDs in this range have the same number of decimal digits (19), lexicographic order equals numeric order for same-score members. Ordering is therefore always correct.
func MemberToID ¶
MemberToID parses a sorted-set member back to int64.
func MessageKey ¶
MessageKey returns the Redis string key for a single cached dto.Message.
