can't find init table meta for {} with position : {}

Error message

can't find init table meta for {} with position : {}

What it means

Thrown as CanalParseException when processTableMeta(startPosition) returns false, meaning the table metadata needed at the start position could not be resolved. Even though a binlog position was found, Canal could not load the schema/table info required to decode row events correctly, so it refuses to start to avoid corrupt parsing.

Solutions

  1. Ensure the canal MySQL user has SELECT on the tables being replicated (canal.instance.filter.regex/table).
  2. Confirm the tables in the filter still exist on the source with the same names.
  3. If using TSDB, clear or rebuild the TSDB snapshot (h2/db) for the destination so meta is re-fetched.
  4. Align canal.instance.filter.regex to include the tables present in the binlog at the start position.

Example fix

# before
canal.instance.filter.regex = .*\\..*

# after (only replicate existing tables and grant SELECT)
canal.instance.filter.regex = mydb\\.(orders,customers)
GRANT SELECT ON mydb.* TO 'canal'@'%';
Defensive patterns

Strategy: validation

Validate before calling

-- confirm the table exists and canal can read it
SELECT COUNT(*) FROM information_schema.tables WHERE table_schema='mydb' AND table_name='orders';
SHOW COLUMNS FROM mydb.orders; -- fails without SELECT

Try / catch

try { parser.start(); }
catch (CanalParseException e) {
    if (e.getMessage().startsWith("can't find init table meta")) { rebuildTsdbSnapshot(destination); parser.start(); }
    else throw e;
}

Prevention

When it happens

Trigger: Right after a valid startPosition is found, AbstractEventParser calls processTableMeta(startPosition); a false return triggers this. With TSDB enabled this delegates to tableMetaTSDB; without it, the table-meta fetch against the source DB fails or the table is not in the filter.

Common situations: The table referenced by the start position no longer exists at the source (dropped/renamed), the canal user lacks SELECT on the table, the filter (canal.instance.filter.regex/table) excludes the table so meta is skipped, or TSDB snapshot is missing/corrupt for that position. Also after a DDL that renamed the table between the binlog position and now.
