Failed Schema Sync¶

The total binary footprint of all ScyllaDB columns, tables, etc., must fit a single commit log segment size divided by two. If this requirement is not met, schema sync may fail. The error message may resemble the following:

Oct 06 22:12:47 ip-172-21-1-122 scylla[1213356]:  [shard 0] storage_service - Fail to pull schema from 172.21.2.210: std::invalid_argument (Mutation of 27837439 bytes is too large for the maximum size of 16777216)
Oct 06 22:12:47 ip-172-21-1-122 scylla[1213356]:  [shard 0] migration_manager - Pulling schema from 172.21.2.210:0

In such a case, you may need to increase the commitlog segment size limit. To do this, go to /etc/scylla/scylla.yaml and set the commitlog_segment_size_in_mb parameter to a higher value.
