EstimateBatchSizeBytes returns an estimated amount of bytes needed to store a batch in memory that has column types vecTypes.

GetBatchMemSize returns the total memory footprint of the batch.

GetFixedSizeTypeSize returns the size of a type that is not variable in size; e.g.

NewAllocator constructs a new Allocator instance with an unlimited memory account.

NewLimitedAllocator constructs a new Allocator instance which works with a limited memory account.

AccountingHelper is a helper that provides a reasonable heuristic for reallocating batches with ResetMaybeReallocate() function.

Allocator is a memory management tool for vectorized components.

SetAccountingHelper is a utility struct that should be used by callers that only perform "set" operations on the coldata.Batch (i.e.
