Examples of OTxSegment

com.orientechnologies.orient.core.storage.impl.local.OTxSegment
Handles the records that wait to be committed. This class is not synchronized because the caller is responsible of it.

Record structure:
+--------+--------+---------+---------+----------------+-------------+---------+ | STATUS | OPERAT | TX ID . | CLUSTER | CLUSTER OFFSET | DATA OFFSET | VERSION | | 1 byte | 1 byte | TX ID . | 2 bytes | 8 bytes ...... | 8 bytes ... | 4 bytes | +--------+--------|---------+---------+----------------+-------------|---------+ = 28 bytes
At commit time all the changes are written in the TX log file with status = STATUS_COMMITTING. Once all records have been written, then the status of all the records is changed in STATUS_FREE. If a transactions has at least a STATUS_FREE means that has been successfully committed. This is the reason why on startup all the pending transactions will be recovered, but those with at least one record with status = STATUS_FREE.
