branch-3.0: [opt](rowset meta) truncate segments key bounds if too large to avoid RowsetMetaCloudPB exceeds fdb's 100KB limits (#45287) - #51595
Merged
Conversation
… `RowsetMetaCloudPB` exceeds fdb's 100KB limits (apache#45287) In cloud mode, `RowsetMetaCloudPB` will be stored as a value in fdb. Segment key bounds is a member of `RowsetMetaCloudPB`. When the key columns has long data, segment key bounds may be very large, causing the size of `RowsetMetaCloudPB` be larger than the fdb 100KB limit, and will cause load txn fail when put `RowsetMetaCloudPB` KV in fdb. This PR add a config `segments_key_bounds_truncation_threshold` to limit the max length of segment key bounds to avoid the problem. Segment key bounds which are larger than the value of this config will be truncated. The config will take effect when rowset is generated(load/schema change/compaction/snapshot). **Note that as long as the config `segments_key_bounds_truncation_threshold` has ever been turned on, cluster downgrade and backup restore are not supported any more.**
