Ráthaíonn Kafka eagrú laistigh de bharúntúil ach ní laistigh ar bharúntúile — coincheap ríthábhachtach. Chun eagrú a fháil do thúairiscí gaolmhara, déanann tú iad a threorú go dtí an bharúntúil céanna (trí an eochair chéanna). Tá sé tábhachtach eagrú a thuiscint do chúrsaí a bheith ceart.
Eagrú in aghaidh bharúntúile
Kafka guarantees:
✓ ORDER WITHIN a partition → events in a partition are strictly ordered (by offset);
consumers read them in order
✗ NO order ACROSS partitions → events in different partitions have no relative order
guarantee (they're processed in parallel by different consumers)
→ this is a FUNDAMENTAL Kafka property (and a common source of misunderstanding)
