bytespace-batchlog

Write-ahead logging for transactions in a bytespace.

Write operations are given a monotonically increasing id and written to transaction log. Batches are processed asynchronously and added to the store. By default, query methods withheld until batch processing is complete for the commit which was current at the time the query is received.

Batch processing pipeline

The batch processing pipeline exposes extensions points to allow pre-commit hooks to do additional work before committing to the transaction log, and post-commit hooks to do additional work after a transaction. Work can be isolated to specific subspaces, allowing heavyweight analytical processing to proceed without blocking queries in hot-path or transaction-heavy spaces. Analytical work can be delegated to subprocesses or even remote machines. Work on multiple commits can be batched together, and monotonically increasing batch ids can be leveraged to allow reads on possibly stale data to be held, e.g. until the next "

antennas

• what can you deduce of dBi? how much does it affect performance?
• seems most antennas have coax cables, how do I connect an antenna to e.g. WNDR4300 or other devices that have built in antennas?
• how cheap antennas can you use to get by?
• what type of outdoor antenna is best for building the backbone in a mesh network?
